External Email - Use Caution
Hello,
I have 2 groups (group 1 = 3 members, group 2 = 12 members) and I did like to regress out the effects of groups + other variables by using doss. However, whenever I specify doss with the mri_glmfit command, it gives me an error message (see below). I saw that others have experienced similar issues without any solutions. How can we solve this? Any insight is appreciated.
Best, Paul
mri_glmfit command:
mri_glmfit --y ../../freesurfer/subjects/tracula_output/stats/mcp.avg16_syn_bbr.FA.nii.gz --fsgd dti_RPQ_3.fsgd doss --C dti_RPQ.mtx --o mcp_FA.glmdir --save-eres --nii.gz
design.mtx:
0 0 0 0 0 0 0.5
Terminal output:
