Dear all,

Using FreeSurfer 7.1.1, I made my analysis file with the following (I assume -nksip should be in the number of TRs and not in seconds):
mkanalysis-sess -analysis retino_surf_pr_lh_sm0 -surface self lh -fwhm 0 -fsd bold -per-run -retinotopy 32 -spmhrf 0 -paradigm retino.par -TR .800 -nskip 10 -mcextreg -runlistfile retino_all_runs.txt

Then I ran the glm with the following:
selxavg3-sess -sf sessid_retino -df sessdir -analysis retino_surf_pr_lh_sm0

But I kept getting the following error message at the end of the log file:
