log2 RSEM data with finite and non-negative

Hello All

I am analyzing 1 RNAseq data which has been deposited in GEO as the RSEM upper quantile normalized data. I used limma-voom for DEGs between groups using galaxy. The error which I have got was:
[1] “Extracting counts”
Error in cpm.default(data$counts) :
library sizes should be finite and non-negative
Calls: cpm -> cpm.default
Execution halted

Can anyone suggest me how to handle this data?

Thanks in advance
