Issue with TransCommuProfile step 5 softmax for ligand

[LaviCor]

Hi all,

I am running into an issue when trying to follow along the instructions to analyse ligand-receptor interactions using CellCall. when running the "TransCommuProfile" command, I am faced with the error: "Error in expr_mean[intersect(ligand_symbol, detect_gene), ] : incorrect number of dimensions".

my console output looks like this:

I am using mouse scRNAseq data analysed previously in Seurat, (I used the following code to create the CellCall object: "scLR <- CreateObject_fromSeurat(Seurat.object= sc, data_source="UMI", Org = 'Mus musculus')" )

Would really appreciate any help or insights!

I got the exact same error as you! I don't think it's a species problem, because I'm using human data, and the error is also reported. Also it's not a question of method.If you solve this problem, can you tell me how to solve it?I would be grateful.

Same here. Please let me know if you already find the solution. many thanks!

老铁，第一步CreateObject_fromSeurat函数中cell_type=什么你们没有选对，先head一下你们的seurat对象看看细胞类型在哪一列，再在cell_type=中填入列名。这样运行的结果再在TransCommuProfile函数中运行才不会报错。
