comparing dataset error in netAnalysis_signalingChanges_scatter

[Leob44]

Hello,
I am following the comparing dataset vignette on cellchat v2. When I try to apply the function netAnalysis_signalingChanges_scatter I have an error "$<-.data.frame(tmp`, "specificity", value = 0) : replacement has 1 rows, data has 0"

Here is the command I used:

g1 <- netAnalysis_signalingChanges_scatter(cellchat, idents.use = "NK")

I have only two conditions in my merged cellchat object as in the tutorial and "NK" is indeed present in the cellchat@idents$joint

I had to go inside the function code. In line 73 of the function, there is:
mat1 <- mat[rownames(mat) %in% signaling, , drop = FALSE]
The rownames of "mat" are not fitting the "signaling" function
print(signaling)

print(rownames(mat)

All of this is resulting into an empty intermediate matrix and thus the function can not go further. Still investigating
