Group comparison #30
Comments
@JDavies95 Are you using CellPhoneDB input to CrossTalkeR? How many cell types do you have? I need more details about what you have. |
I came across exactly the same error in one of my comparison. I also want to know what happens. It seems it's due to the prcomp. Maybe all rows have the same variance? |

Hi, I am trying to do the analyse comparing disease to control but i keep receiving this error:
R[write to console]: Error in prcomp.default(all_both, center = TRUE, scale = TRUE) :
cannot rescale a constant/zero column to unit variance
Error in prcomp.default(all_both, center = TRUE, scale = TRUE) :
cannot rescale a constant/zero column to unit variance
Any advice on what I may be doing wrong?
Thanks!
