Thanks, Doug for that quick response!
Does mask.mgh varies between different set of subjects and (or) different set of contrasts for a given hemisphere? Since fsavearge doesnt change, the mask that is used for statistical comparisons should change neither unless I change --trgsubject to some other. Am i right?
thanks
regards

Hi,
I am just curious whether the mask.mgh file returned in glmdir folder created from lh.cortex.label?
In part. It will also include any voxels that have 0 values in any of the inputs (--y)
If so, how can I create my own surface mask from the label file? (mri_label2vol and mri_vol2surf ?)
mri_label2label with the --mask option
Second: How can I compare the subcortical volumes between the 2 groups using glm tools in freesurfer? Specifically, how do I call mris_preproc and mri_glmfit?
Run asegstats2table to create a table, then run mri_glmfit as before but with --table instead of --y
I appreciate your response.
Thank you
