Error in processing xcell analysis #78
Comments
[1] "Num. of genes: 0" This means that the rownames in your data are not gene symbols. xCell assumes that you are using gene symbols and not some other gene ids. Best, |
Thank for your reply! |
The same problem also occurs here, only endured background correction, rma normalizaion and gene expression index calculation of probe intensities. |
For some reason you have an extra space in all the gene names. rownames(a) = gsub(' ','',rownames(a)) should fix that... |
Apologize for my silence for weeks, and thank for your reply from the bottom of my heart!
The same data can be analysied in the web xcell, so i wonder what's wrong and how can i figure it out. (i have updated all packages and changed network enviroment) |
It's an issue with the matrixStats package. It made havoc throughout many packages. You need to upgrade your BioConductor and all associated with packages. Best, |
I conquer it! tooooooooooo much appreciation for you!!! |
Hi,
I have been interested in for immune infiltration analysis for a while and impressed by xcell.But many RNA expression dataset i collected from GEO cannot perform xcell and it replies like
I have checked the normalization process and each dataset contains enough gene(~20000).I cannot firure out why this happened and it have bothered me some days:(
I am dull, please tell me!
