Hello community,
My apologies if it is a basic question, I just started with the tutorial recently. I have a quick question about the Zscore calculation.
I am following the Galaxy tutorial for Zscore calculation (Referencebased RNASeq data analysis in " Handson: Compute the Zscore of all genes"). As input I am using normalized counts for some differential expressed genes but after the first step of table compute I am getting the same values as output. In theory, I should get as an input the mean values per row, right?
Here the steps that I followed in table compute tool:

“Input Single or Multiple Tables”:
Single Table
 paramfile “Table”:
Normalized counts file on ...
(output of DESeq2 tool) 
“Type of table operation”:
Perform a full table operation

“Operation”:
Custom

“Custom expression on ‘table’, along ‘axis’ (0 or 1)”:
table.sub(table.mean(1), 0)

“Custom expression on ‘table’, along ‘axis’ (0 or 1)”:

“Operation”:
 paramfile “Table”:
Many thanks in advance for your feedback.
