Hi,
I am interested in looking at groups differences (3 groups) in percent thickness change. I want to use mri_glmfit to analyze but I am unclear on what I should include on my fsgd file. Can you please provide an example?
Also The example provided on the fswiki under Option mri_glmfit doesn't call for an fsgd file.
long_mris_slopes --qdec long.testretest.qdec \
--meas thickness \
--hemi lh \
--sd $SUBJECTS_DIR \
--do-pc1 --do-label \
--generic-time \
--fwhm 15 \
--qcache fsaverage \
--stack-pc1 lh.testretest.thickness-pc1.stack.mgh \
--isec-labels lh.testretest.fsaverage.cortex.label
mri_glmfit --osgm \
--glmdir lh.testretest.thickness-pc1.fwhm15 \
--y lh.testretest.thickness-pc1.stack.fwhm15.mgh \
--label lh.testretest.fsaverage.cortex.label \
--surf fsaverage lh
