Getting error in buildNhoodGraph

[sepehrgolriz]

Hi,

I am getting an error while using the buildNhoodGraph function. The error is

Error in if (any(i < 0L)) { : missing value where TRUE/FALSE needed In addition: Warning message: In int2i(as.integer(i), n) : NAs introduced by coercion to integer range

However, there is no NA in the object: any(is.na(reducedDim(traj_milo))) [1] FALSE

These are the properties of the object:

dim(traj_milo) [1] 12136 732835

nhoods_matrix <- nhoods(traj_milo) dim(nhoods_matrix) [1] 732835 99589

Could anyone help me with this? The size of the dataset could be a problem?

Thanks a lot for your kind help in advance.

Hi,

Even with smaller dataset I get the same error:

small_traj_milo <- traj_milo[1:1000, ]

small_traj_milo <- buildNhoodGraph(small_traj_milo) Error in if (any(i < 0L)) { : missing value where TRUE/FALSE needed In addition: Warning message: In int2i(as.integer(i), n) : NAs introduced by coercion to integer range

Any help would be appreciated!

[MikeDMorgan]

Always provide the output of sessionInfo() and the code leading up to the point of the error.

Yes Sir. Sorry for my bad!

Firstly, a k=4 is extremely small for building a kNN-graph given you have >700k cells. You are then using a different value for k in the nhood definition, so you most likely don't have many connections between your cells. Inspect your nhoodSize histogram and aim for ~5xS, where S is the number of experimental samples, OR a median nhood size of ~100 if you have lots of samples, i.e. >20.

Secondly, subsetting the Milo object on the rows, subsets on the genes, not the cells.

[sepehrgolriz]

First of all, thanks a lot for your kind help.

Despite the changes I did in the code, I am still getting the same error:

Here is the changes:

traj_milo <- buildGraph(traj_milo, k = 40, d = 40) # Increased k Constructing kNN graph with k:40 traj_milo <- makeNhoods(traj_milo, prop = 0.12, k = 40, d = 40, refined = TRUE, refinement_scheme = "graph") Checking valid object Running refined sampling with graph traj_milo <- countCells(traj_milo, meta.data = data.frame(colData(traj_milo)), samples = "orig.ident") Checking meta.data validity Counting cells in neighbourhoods plotNhoodSizeHist(traj_milo)

Check the median neighborhood size

median_nhood_size <- median(colSums(nhoods(traj_milo))) print(paste("Median neighborhood size:", median_nhood_size)) [1] "Median neighborhood size: 106"

traj_milo <- buildNhoodGraph(traj_milo) Error in if (any(i < 0L)) { : missing value where TRUE/FALSE needed In addition: Warning message: In int2i(as.integer(i), n) : NAs introduced by coercion to integer range

Any chance to have more of your kind help?

Thanks a in advance.

[MikeDMorgan]

Can you run the following code without error:

nh_intersect_mat <- miloR:::.build_nhood_adjacency(nhoods(traj_milo))

[sepehrgolriz]

Unfortunately no! Got the same error as before:

nh_intersect_mat <- miloR:::.build_nhood_adjacency(nhoods(traj_milo))

Error in if (any(i < 0L)) { : missing value where TRUE/FALSE needed In addition: Warning message: In int2i(as.integer(i), n) : NAs introduced by coercion to integer range

[sepehrgolriz]

Dear Mike, I was wondering if I can have more of your kind help?!

Thanks a lot in advance.

[MikeDMorgan]

How many nhoods do you have in this object, and what is the provenance of the data?
