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 Original post: 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 Damien MARIE Post-doctoral Fellow damien.ma...@unige.ch +41 22 379 08 49 ----------------------------------------------------------------------------------------- Brain and Language Lab Department of Clinical Neuroscience Biotech Campus 9 Chemin des Mines 1202 Genève http://www.brainandlanguagelab.org -----------------------------------------------------------------------------------------
