Hello All,
I am having an issue using SurfClust. I do not know what surface filename would put after -surf_A. I did an analysis on surface data and generated a .gii file from 3dANOVA2. I used the fsaverage to normalize the T1mprage files to, but now I'm not sure what input I should set for -surf_A.

SurfClust -spec fsaverage_lh.spec -surf_A -input ANOVALhemimencycthick.gii 1 -rmm 2 -thresh_col 1 -thresh 2.87 -amm2 98 -prefix LhemimencycthickPhasemainF05 -out_clusterdset

Thank you,
Tim
