Landmarks tps format

[EveTC]

Hi Steven (just me again! hehe),

I was just wondering if patternize accepts landmarks in a tps format? For example files created using the programme tpsUtil and tpsDig? This would save having to export the x&y coordinates seperately for hundreds of individuals as it is automatically saved into one file?

I hope you are well and look forward to hearing from you. Thank you, Eve

[StevenVB12]

Hi Eve,

I haven't been using tips myself. Could you share me an example with three images? I will try to add that option.

Cheers,

Steven

Hi Steven,

Thank you so much for your quick reply.

Here is an example of one of my calibrated (using patternize :D) images that I want to set landmarks on

I make a tps file using tpsUtil and place 13 landmarks on each of these individuals using tpdDig following the tutorials (1 and 2) found here: [https://www.youtube.com/channel/UC2yXTBdhPgVL6H7hW8rMcFw]

which looks like this:

and produces a file with this format (copied it into a text editor as I cant upload a .tps file to GitHub for some reason): practice_etc.txt

Let me know if you need anything else. Thank you so much, Eve

[StevenVB12]

Hi Eve,

Thanks for the list. I added the option to use a tps landmark file to the makeList function (please reinstall patternize from github for this to work).

It works as follows:

landmarkList_tps <- makeList(IDlist, 'landmark', format = 'tps', tpsFile = 'tps_filename')

Please let me know if it works correctly. I think in your further commands you should set adjustCoords = FALSE for tps landmarks.

Cheers, Steven

[StevenVB12]

Also, note that your IDlist should have the same order as the samples in the tpsFile.

Steven

[EveTC]

Hi Steven,

Amazing, thank you so much! I will give it a go shortly. I realised I didnt set a scale on my example before (which I will be doing) which makes the file format as so: practice_scale_etc.txt Does this change what you have just done? So sorry if it does!

It is amazing how quick you always solve my queries - thank you so so much. Eve

[StevenVB12]

I don't think it should matter, but let me know if things don't work!

Steven

[EveTC]

Hi Steven,

So I have run it with the landmarks input as a tps format. Firstly with the scale and secondly without the scale in the tps.

The landmarkList_tps_scale <- makeList(IDlist, 'landmark', format='tps', tpsFile= './photos/GBS pops/tps_prac/practice_scale_etc.TPS') is accepted without errors.

However when I plot the summed rasters using: rasterList_lanK_scale <- patLanK(imageList, landmarkList_tps_scale, k=3, adjustCoords = FALSE, plot=T, resampleFactor = 10, removebgK = 220) summedRaster_lanK_scale <- sumRaster(rasterList_lanK_scale, IDlist, type = 'k') colfunc <- inferno(100) plotHeat(summedRaster_lanK_scale, IDlist, colpalette = colfunc, adjustCoords = FALSE)

It produces this with the scale in the landmarks folder:

It produces this without the scale:

Here is my script if you need: tps_landmark_test_script.txt

Have I made a silly mistake? I am just trying it now with landmarks set the original methos for these three individuals to see if it works.

Thanks, Eve

[EveTC]

I have just tried it with the normal method of importing landmarks and get the same output as above when I do not have the scale in the tps format. What have I done wrong?

Thanks, Eve

[StevenVB12]

Hi Eva,

Could you share me a couple of images with the landmarks and code for me to try? Maybe you can send them to my email vanbelleghemsteven at hotmail.com.

Hi Eve,

I had to make a couple of improvements to allow for the correct plotting when using tps files (please reinstall).

In the process I also realized I could improve the k-means background extraction so that the background is completely ignored when choosing the k-means clusters.

I would also advice you to transform your images to one reference image (example at the end below). This will make your life easier when you want to compare sets of images and you have transformed all those images to the same reference (using meanshape that can get quit complicated).

Let me know if this code works for you

# make list with images
IDlist <- c('PA_1_WW_02', 'PA_1_WW_03', 'PA_1_WW_04')
prepath <- 'photos/'
extension <- '_D_calibrated.jpg'
imagelist <- makeList(IDlist, 'image', prepath, extension)

# load landmarks

landmarkList_tps_scale_FIJI <- makeList(IDlist, 'landmark', prepath = 'landmarks/', extension = '_D_land.txt')
landmarkList_tps_scale_TPS <- makeList(IDlist, 'landmark', format='tps', tpsFile= './landmarks/practice_etc.TPS')

                                           resampleFactor = 3, res = 150, cropOffset = c(10,10,10,10))

Hi Eve,

I can't reproduce your error from the script that I gave you earlier. In your TotalList, do all rasters have the same resolution?

target <- landmarkList_tps_scale_TPS[[1]]
cartoon <- read.table('cartoon/PA_1_WW_02_cartoon.txt',h=F)

RGB <- c(105,90,72)
rasterList_lanK_tps_TPS <- patLanRGB(imagelist, landmarkList_tps_scale_TPS, RGB, colOffset = 0.15, adjustCoords = FALSE, plot= 'stack', transformRef = target,
                                     resampleFactor = 3, res = 150, cropOffset = c(10,10,10,10))

summedRaster_lanK_tps_TPS <- sumRaster(rasterList_lanK_tps_TPS, IDlist, type = 'RGB')

colfunc <- inferno(100)

plotHeat(summedRaster_lanK_tps_TPS, IDlist, colpalette = colfunc, adjustCoords = FALSE, refShape = 'target', landList = landmarkList_tps_scale_TPS,
         imageList = imagelist, outline = cartoon, cartoonID = 'PA_1_WW_02', plotCartoon = TRUE, cartoonFill = 'black', cartoonOrder = 'under', format = 'tps')

[EveTC]

Hi Steven,

This script works perfectly! Thank you so much.

Can I just confirm that when you use registration instead of landmarks (as I am wishing to compare the outputs) you do not need the alignment step to enable comparisons between populations? The registraion does this itself to the provided target image?

From my preliminary investigations it seems the target image can change the output of a PCA from the registration method quite substaintially? As such how do you suggest to selcet the target image and should it be part of one of the populations you are comparing? Is this the advantage of using landmarks over registration?

Cheers

[StevenVB12]

Hi Eve,

with registration, you do not need landmarks. The registration looks for sharp patterns of contrast in the images and uses that to align them. That also means that if there is some artifact in your background that is very consistent, the algorithm might pick that artifact to align. Also, the registration only uses a linear transform (size, shear and orientation), whereas the landmarks uses TPS, which allows to fit more complex shape changes. The latter would explain the less perfect alignment in the following example:

target <- imagelist[['PA_1_WW_02']]

RGB <- c(105,90,72)
rasterList_regRGB <- patRegRGB(imagelist, target, RGB, colOffset = 0.15, plot= 'stack', resampleFactor = 3)

summedRaster_regRGB <- sumRaster(rasterList_regRGB, IDlist, type = 'RGB')

colfunc <- inferno(100)

plotHeat(summedRaster_regRGB, IDlist, plotCartoon = TRUE, refShape = 'target', outline = cartoon, 
         imageList = imagelist, cartoonID = 'PA_1_WW_02', flipOutline = 'y', flipRaster = 'x',
         cartoonFill = 'black', cartoonOrder = 'under', colpalette = colfunc)

TotalList <- rasterList_regRGB
popList <- list(IDlist)
symbolList <- c('19')
colList <- c('red')
pcaOut <- patPCA(TotalList, popList, colList, symbolList = symbolList, plot = TRUE, plotType = 'points', 
                 plotChanges = TRUE, PCx = 1, PCy = 2, plotCartoon = TRUE, refShape = 'target', outline = cartoon, 
                 imageList = imagelist, cartoonID = 'PA_1_WW_02', flipOutline = 'y', flipRaster = 'x', 
                 normalized = TRUE, cartoonFill = 'black', cartoonOrder = 'under', legendTitle = 'Predicted')

[StevenVB12]

For registration, you should always use the same target image if you want to compare populations.

Hope this helps.

Steven

[EveTC]

Hi Steven,

Ok, thank you for your help. I realised that the error was because one of my populations had a different resample factor.

I have just tried to increase the number of my samples using landmarks following your example script. However when I run imageList_aligned_TPS <- alignLan(imageList_CoreNorth_LF, landmarkList_core_n_TPS, transformRef = target, adjustCoords = FALSE, plotTransformed = T, resampleFactor = 3, maskOutline = outline_LF_CNM6_D, cartoonID = 'CNM6_D', format = 'tps') and recieve this error: Error in raster::extent(imagelist[[cartoonID]]) : object 'imagelist' not found

Although I have set the imageList by this: imageList_CoreNorth_LF <- makeList(IDlist_CoreNorth, 'image', prepath_CNM_dorsal_crop, extension)

I have checked that the IDList samples are in the same order as those in the TPS file. ANy ideas where I made a mistake?

[StevenVB12]

Hi, my best guess is the the cartoonID 'CNM6_D' is not among the images in the imagelist.

Steven

[EveTC]

Its definetly there. Ill keep playing and let you know if I find the solution. Thank you for all your help Steven

Eve

[StevenVB12]

If you keep getting the error, please share me reproducible code on dropbox.

Cheers, Steven

[EveTC]

I can't work out where the error is coming from. I'm so sorry to be a pain!

I have shared a dropbox folder with you, using the email address you provided before.

[StevenVB12]

Hi Eve,

sorry if you have been spending a lot of time on this, because this was totally caused by typos in the added tps code! (please reinstall)

I do notice that your landmarks are scaled (in the range of 0-2). I'm afraid that won't work either as the XY coordinates should be be in pixel coordinates (in the range of 0-4000).

Cheers, Steven

[EveTC]

Hi Steven,

Ah Im am relieved as I thought it may have been a silly error that I made myself. No worries at all!

Oh I set them the scale in tpsDig. Does the code use the scale? Is this why the summedraster looks like this for me?

Also couple more questions (sorrry!):

1. Is there a way to use alignLan() with "remove background" instead of mask outline? You suggest that remove background is more suitable to me but I cant seem to use that and not the meanshape?
2. For Landmarks do I align populations to the same target individual for comparison like registration or seperately per population?

Thank you again Eve

[StevenVB12]

Hi Eve,

If you just want to mask the background, you should get the same result with patLanK as with alignLan + K.

I could add the meanshape option to alignLan if you want, but I think down the line things will be easier if you choose one image and use that as your reference. I would then align batches of samples that belong to the same population. The resulting rasterlists can then easily be compared or used in the PCA function and all match the same reference image. The latter is necessary to be able to compare populations.

The code does not use scale. But it shouldn't be to hard to get the coordinates from the scale: x = scale raster::extent(image)[2] Y = scale raster::extent(image)[4]

Fantastic, thank you so much. Yes don't worry about putting mean shape in thank you though. I think it's looking good!

Should the target individual be separate from all the populations, ie not included in the populations themselves?

[StevenVB12]

No specific requirement. I would take the one for which you drew the outline (has to be the same image).

Hi Steven, Thank you so much for all your help.

In the alignLan function I recieve this error if the target individual is not included in the imageList of a population: Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘extent’ for signature ‘"NULL"’ Does this mean I have to include the target individual in both populations? Surely this will mean that in the PCA output one point will be identical and skew the points towards similarity?

[StevenVB12]

Hi Eve,

Sorry, I hadn't considered this option. I think I've fixed this.

You can now load a reference image as:

targetIm <- raster::stack("photos/CNM1_D_calibrated.jpg")

And then set cartoonID = NULL and refImage = targetIm.

imageList_aligned_TPS_noscale <- alignLan(imagelist_CN[c(2:4)], landmarkList_CN_noScale_TPS[c(2:4)], transformRef = target, = FALSE, plotTransformed = T, resampleFactor = 10, maskOutline = cartoon,                                           cartoonID = NULL, format = 'tps', refImage = targetIm)

Let me know if it works!

Steven

[EveTC]

Hi Steven,

No worries, thank you for your speedy response again. Does this image need landmarks of its own?

Cheers, Eve

[StevenVB12]

Yes, you still have to provide the landmarks to transformRef.

Hi Steven,

It is working perfectly up until plotHeat() where I get this error: Error in imageList[[cartoonID]] : attempt to select less than one element in get1index

Cheers, Eve

[StevenVB12]

Aj, sorry! I fix one thing and break the next. It should work now.

In plotHeat you'll have to set refImage = targetIm, while transformRef should be set to the reference landmarks.

I also made removebg work for alignLan. I noticed that having an upper RGB boundary does not work perfectly for your images as the shadows around the wing remain. If you are planning to use this I could implement an RGB range for background extraction which might work better.

Let me know!

Steven

[EveTC]

No worries - thats coding for you! Haha

I can't see the transformRef option in plotHeat() but it is working now - thank you! Although as you say onto the next problem: When I try to plot the PCA using: pcaOut <- patPCA(TotalList_land_outTarget, popList_land_outTarget, colList_land_outTarget, symbolList = symbolList_land_outTarget, plot = TRUE, plotType = 'points', plotChanges = TRUE, PCx = 1, PCy = 2, plotCartoon = TRUE, refShape = 'target', refImage= targetIm, outline = cartoon, flipOutline = 'y', imageList = imageList_CoreNorth_LF, cartoonID = NULL, normalized = TRUE, cartoonFill = 'black', cartoonOrder = 'under', legendTitle = 'Predicted')

I get this error and warnings: Error in plotHeat(mapMix/max(abs(xMi)), rList, plotCartoon = plotCartoon, : if cartoonID not in image list, please provide image to refImage argument. In addition: Warning messages: 1: In plot.window(...) : "refImage" is not a graphical parameter 2: In plot.xy(xy, type, ...) : "refImage" is not a graphical parameter 3: In axis(side = side, at = at, labels = labels, ...) : "refImage" is not a graphical parameter 4: In axis(side = side, at = at, labels = labels, ...) : "refImage" is not a graphical parameter 5: In box(...) : "refImage" is not a graphical parameter 6: In title(...) : "refImage" is not a graphical parameter

Oh thank you - I haven't tried remove background with alignLan() yet but I do think it is better than maskoutline for me due to damage on some of the wings? If you think that would help remove the shadows then that would be amazing if you could! I am going to have a play at alignLan() with remove background now 😄

[StevenVB12]

I meant refShape = target (landmark matrix of reference image), but 'target'might work as well.

I fixed the patPCA function and will change the background function later today.

Thanks for your perseverance with the errors!

Steven

[EveTC]

You are amazing! - thank you so much 😄 No thank you for your perseverance with all my needs!

[EveTC]

Re-tried the patPCA() - using same code as above- this error popped out: Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘extent’ for signature ‘"character"’ Sorry! :/

[StevenVB12]

Hmm, hard to see where the problem is happening. Di you reinstall? I ran the command like this:

pcaOut <- patPCA(TotalList_land_outTarget, popList_land_outTarget, colList_land_outTarget, symbolList = symbolList_land_outTarget, plot = TRUE, plotType = 'points', plotChanges = TRUE, PCx = 1, PCy = 2, plotCartoon = TRUE, refShape = 'target', refImage= targetIm, outline = cartoon, flipOutline = 'y', imageList = imagelist_CN, cartoonID = NULL, normalized = TRUE, cartoonFill = 'black', cartoonOrder = 'under', legendTitle = 'Predicted')

Could you show me traceback() output after the error occurs?

Steven

Ah not sure what I did - but its working now! Sorry! Thanks, Eve

[StevenVB12]

Great. I now added removebg possibilities with RGB. (Note that I changed removebgK to removebg for both patLanK and alignLan.

You can pick a bg color like so:

bgRGB <- sampleRGB(imagelist_CN[[1]], resampleFactor = 5, type = 'area')

and then add the following to alignLan:

removebg = bgRGB, removebgColOffset = 0.12

Note that this will still work:

removebg = 220

Hope this helps!

Ooo Ill give it a try...

Ah I get this error: Error in if (!c2) { : missing value where TRUE/FALSE needed

[StevenVB12]

What function and command?

Sorry yes,

I ran and followed the instructions bgRGB <- sampleRGB(imageList_CoreNorth_LF[[1]], resampleFactor = 5, type = 'area') and then: CN_rmB_align <- alignLan(imageList_CoreNorth_LF, landmarkList_CN_noScale_TPS, transformRef = target, adjustCoords = FALSE, plotTransformed = T, resampleFactor = 3, format = 'tps', refImage = targetIm, removebg = bgRGB, removebgColOffset = 0.15, res = 150)

It adds all the images to the array and prints out the first image and then stops

[StevenVB12]

Hmm, looks correct. Any more info on the error?

this is what traceback() outputs after the error appears: 11: validityMethod(as(object, superClass)) 10: isTRUE(x) 9: anyStrings(validityMethod(as(object, superClass))) 8: validObject(.Object) 7: initialize(value, ...) 6: initialize(value, ...) 5: methods::new("RasterLayer", extent = ext, nrows = nrows, ncols = ncols, crs = crs) 4: .local(...) 3: raster::raster(ncol = inCols, nrow = inRows) 2: raster::raster(ncol = inCols, nrow = inRows) 1: alignLan(imageList_CoreNorth_LF, landmarkList_CN_noScale_TPS, transformRef = target, adjustCoords = FALSE, plotTransformed = T, resampleFactor = 3, format = "tps", refImage = targetIm, removebg = bgRGB, removebgColOffset = 0.15, res = 150)

I don't know if this helps?

[StevenVB12]

Ah, I this case, res has to be a xy vector: res = c(150,150)

[EveTC]

It seems to be working! 😄 Its running the alignLan() now.

Thanks again Steven!

[EveTC]

It works! Athough I get these warnings: Warning messages: 1: In doTryCatch(return(expr), name, parentenv, handler) : restarting interrupted promise evaluation 2: In doTryCatch(return(expr), name, parentenv, handler) : restarting interrupted promise evaluation 3: In doTryCatch(return(expr), name, parentenv, handler) : restarting interrupted promise evaluation 4: In doTryCatch(return(expr), name, parentenv, handler) : restarting interrupted promise evaluation 5: In doTryCatch(return(expr), name, parentenv, handler) : restarting interrupted promise evaluation 6: In doTryCatch(return(expr), name, parentenv, handler) : restarting interrupted promise evaluation

Continuing to do next steps now

[StevenVB12]

That might indicate that for those samples not all k-means clusters were found. There are likely some samples missing in the results (could be maybe because of deleting the background completely in some samples, while not in others). Not that you can combine deleting the background using the outline nd the RGB if that would help.

Ah ok, that makes sense. Will have a look and see if any are removed.

Following the rest of the steps as so: core_north_alignLand_outTarget_rmBkg <- patK(CN_rmB_align, k=3, plot = T, maskToNA = 0) summedRaster_lanK_tps_EN_out_rmbkg_K2 <- sumRaster(core_north_alignLand_outTarget_rmBkg, IDlist_CoreNorth, type = 'k') plotHeat(summedRaster_lanK_tps_EN_out_rmbkg_K2, IDlist_CoreNorth, colpalette = colfunc, adjustCoords = FALSE, refShape = target, refImage = targetIm, landList = landmarkList_CN_noScale_TPS, imageList = imageList_CoreNorth_LF, outline = cartoon, cartoonID = NULL, plotCartoon = TRUE, cartoonFill = 'black', cartoonOrder = 'under', format = 'tps')

It output quite blurry and messy rasters:

Is there a way to improve this? I got rasters like below using mask outline but I think the damage at the bottom of the wing (where it attaches to the body) is altering the PCA.

[StevenVB12]

Strange. Could you share the script and data for that in dropbox? I also think the ones on the bottom look better 😊
