Error with Call Cell Chat

[jonhsussman]

Hello,

I am getting the following error when running "call_cellchat." It runs through as follows, but then displays the error of unused argument (do.fast = TRUE). Have you encountered this error?

liana.cellchat.2 <- liana_wrap(seurat.timepoint2, method = "call_cellchat", idents_col = 'annotations.update')  
Expression from the `RNA` assay will be used
Running LIANA with `annotations.update` as labels!

Hi,

This coercion: allocating vector of size 1.2 GiB seems to be related to RAM issues and/or the CellChat method itself.
If I remember correctly, this is an issue specific to Linux machines.
Perhaps, if RAM limitations are not the issue, you could check the issues posted on CellChat for a potential solution :)

Hope this helps.

Thanks for your reply; the RAM is not an issue on the server so it would likely be an issue related to CellChat. I'll inquire to CellChat about a potential solution to this

Hi, I am having the exact same issue. I looked into the CellChat source code for computeCommunProb() here and it seems like do.fast is not in the function definition. Do you think that is the cause of the issue, or is it something to do with the CMKLR2 gene?
My code:

liana_gpx_cellchat <- liana_wrap(gpx_seurat,min_cells=2,method="call_cellchat")

Error message:

@jonhsussman, did you ever solve this issue?

It was an unused parameter from an old CellChat version that I was using in my pipeline, it is now removed and works with more recent CellChat versions.
