Error in identifyOverExpressedGenes(EarlyPro):

[ChIPseq]

Hi, I encountered a problem when I use the function: identifyOverExpressedGenes in CellChat.
I ensured i run the "subsetData", but my data.signaling matrix only has 0 x 376.
The error message:
Error in identifyOverExpressedGenes(EarlyPro) :
Please check [email protected] and ensure that you have run subsetData and that the data matrix [email protected] looks OK.

okok,i have solve this question. Thanks sqjin.
I try to convert counts data directly into dgCMatrix, use the code:
counts.earlydg <- as(as.matrix(counts.early),"dgCMatrix")
and, I skipped this step:
use the normalize()
