Dear FS team,
I'm currently making a group analysis using the "command-line" group analysis stream in freesurfer. https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisDng [https://surfer.nmr.mgh.harvard.edu/wiki/fswiki_htdocs/common/fslogosmall.png]<https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisDng> FsTutorial/GroupAnalysisDng - Free Surfer Wiki<https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysisDng> surfer.nmr.mgh.harvard.edu Introduction. This tutorial is designed to introduce you to the "command-line" group analysis stream in FreeSurfer (as opposed to QDEC which is GUI-driven), including ... 1) I would like to do a surface based analysis where i'm only investigating a certain area or label - instead of doing a whole brain analysis. This can be done by introducing --label surface_area_of_interest.label when running mri_glmfit. Would this give me different results from doing a whole brain analysis - or would it just exclude the results from outside the label? And how about after clusterwise correction for multiple comparisons? -> is there a better way to do this than following the command-line group analysis stream in freesurfer? 2) When running mri_glmfit-sim i'm investigating the output ending with -voxel.mgh - how do i interpret the results of this file? When investigating the file in freeview what is the meaning of the units when configuring the overlay? Best, Silas
