error when calling identifyOverExpressedGenes function

[xiaozhutou789]

I used the test dataset data_humanSkin and ran the programe as follow. However, there was an mistake like cellchat <- identifyOverExpressedGenes(cellchat) Error in genes.de[[i]] : subscript out of bounds How to fix it ? Many thanks~

subset the expression data of signaling genes for saving computation cost

cellchat <- subsetData(cellchat) # This step is necessary even if using the whole database future::plan("multiprocess", workers = 4) # do parallel

cellchat <- identifyOverExpressedGenes(cellchat) cellchat <- identifyOverExpressedInteractions(cellchat)

project gene expression data onto PPI network (optional)

cellchat <- projectData(cellchat, PPI.human)

and I ran the program on the linux R

@xiaozhutou789 For such errors, I have to say I have no idea. I suggest you to run the sources codes line by line or send me the codes and data that I can replicate your error.
