Dear FreeSurfers,
Sorry for the repost. I’m still trying to extract the residuals of cortical surface area from a qdec analysis with two factors (2 levels) and 2 covariates.
I tried this command line:
mri_segstats --in /home/damien/bin/freesurfer/subjects/qdec/RH_Dys-CT_CSA_AgeGenderWRCSA/y.mgh --sum toto --annot fsaverage rh mc-z.abs.th23.sig.ocn --avgwf RH_Dys-CT_CSA_AgeGenderWRCSA.dat
I’ve got a text file with 9 columns (number of clusters) and 69 lines (number of subjects).
Now I am not 100% sure it’s really the residuals (y.mgh) so I would be glad if somebody could tell me please.
Best,
Damien

Dear experts,
I would like to know what is the best and simplest way to extract cortical surface area and thickness from clusters obtained after a Monte Carlo correction. This is a group comparison I did with qdec including gender as discrete variable + age and mean thickness or whole hemispheric surface area as nuisance factors, so I would like to get the feature residuals after the removal of the covariate effects. I am sorry, I saw several posts about that but for me it’s not completely clear what command line I should use to get tables for this…
Thank you and best, Damien
