Dear All,
I was trying to run 3dMEMA to compare two different groups, using the following lines of code, but when I plot the output in the AFNI GUI no activation is observed:
3dMEMA -prefix G1_G2_COMPARE
-jobs 1
-groups G1 G2
-set G1

I have a .txt file as the CovFile.txt containing two columns, one of them is labeled ‘name’ and contains subject IDs, and the other one is named ‘gender’ and is coded either 0 or 1. I did not use the 3dREMLfit, to obtain the coefficients and their t-stats. [7] and [8] refer to the coefficients and the t-stats for each individual.
I would be grateful if I could ask about your insight about why the output might be empty.
Thank you so much.
