Dear AFNI experts,

I am running stats in AFNI on gyrification index images calculated with Freesurfer. I would like to perform correction for multiple comparisons on the results of the t-test and I am having some problems with slow_surf_clustsim.py to determine the minimum surface size to threshold my results.

The command I am running is
slow_surf_clustsim.py -save_script surf.sim.15_10iter -on_surface yes -uvar spec_file ../../fsaverage_afni/SUMA/fsaverage_afni_lh.spec -uvar surf_vol ../../fsaverage_afni/SUMA/fsaverage_afni_SurfVol+orig. -uvar blur 15.4 -uvar niter 10 -uvar results_dir ./clust_sim_15_10iter

The command correctly writes the script surf.sim.15_10iter, but when I run it I do not get the z.max.pvalue files necessary to determine the minimum surface size for the uncorrected p-value. It seems to me the somehow the command is not able to recognize the list of default p-values. These are the last lines of what I get in the terminal, even though not an error:

Any idea what is happening? This is the list of the files written in the folder:

thank you very much for your help.
