Dear Jin, Thanks for your reply, But how can I remove these values? Or these values affect my data if I remove them?
Thanks and Regards, Surinder Pal

@surinderchd This indicates the problem of your analysis. You should check your analysis and ensure that you use the normalized data without negative values as input of cellchat analysis/.
Dear Jin, Thanks for your quick response, Do I need to normalise data after creating cell chat object, or it should be pre normalised single cell experiment data object?
Thanking you, With Regards, Surinder Pal
