error during auto-seeds selection

[fxpena]

Hi Jinghao,

I'm running min1pipe on a video that I already did rigid motion morrection. It is a tif with 18,000 frames and a frame rate of 20 fps. When it gets to the auto-seeds selection it throws the following error

Error using corr (line 91)
Requires a data matrix X.

Error in sig_sim (line 36)
        sigcor = corr(datasmthf');

Error in seeds_merge (line 21)
    corrdata = sig_sim(datasmth, cutoff, pkcutoff, false);

Error in pix_select (line 171)
    [idusef, datasmthf, datusef, cutofff, pkcutofff] = seeds_merge(maxall,
    iduse, datuse, datasmth, cutoff, pkcutoff, sz, corrthres);

What does this mean? I'm guessing that it datasmth turned out to be an empty matrix but I don't know what that means either. Help?

A similar issue seems to happen with another video.

Index exceeds array bounds.

Error in pix_select (line 134)
    ithres = ctrs(idthres);

Also, before that error was thrown, this warning was thrown.

Warning: Failed to converge in 100 iterations for gmdistribution with 2
components 
> In gmcluster (line 202)
  In gmdistribution.fit (line 102)
  In fitgmdist (line 135)
  In pix_select (line 105)

I think that warning was also thrown for the previous video as well.

Hi Francisco,

This issue is rarely seen and it is hard to find the cause. I am wondering if it is possible to take a look at a couple of frames of the data (a frame or several) to have an idea of the signal density. You can send it to my email address.

Hi Jinghao,

This error happened again with a new video, but I can't remember the solution you found last time. Can you remind me? My email address changed so I can't look for those old emails

Hi Frankie,

I checked the emails and it seems I made some changes to the previous version of the package but I am not sure whether you have tested the new one. If you did then I may need the error message in detail (if there are other types than the one you raised here) or a new sample video.

The error message was virtually identical. The only difference was that the specific line for in pix_select was different (like 200 instead of 171), but the contents of all of the lines in the error were the same. It's just a different video. I'll send you both the original and sample of just 1000 frames in case the error only happens for the larger version.

Hi, I am experiencing the same issues. Would you mind sharing what was the solution that you found for this? thanks in advance!

@NicoGutierrez85 Is the package up to date? Do you still have the same issue?
