Hi,
I am just curious whether the mask.mgh file returned in glmdir folder created from lh.cortex.label?
If so, how can I create my own surface mask from the label file? (mri_label2vol and mri_vol2surf ?)
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?
I appreciate your response.
Thank you
Regards

In part. It will also include any voxels that have 0 values in any of the inputs (--y)

mri_label2label with the --mask option

Run asegstats2table to create a table, then run mri_glmfit as before but with --table instead of --y
I appreciate your response.
Thank you

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

It may change with the data set. Eg, in fMRI, the top of the head my be cut off in one subject and so the top of the head will be out of the mask. Also, there my be some differences in the definition of the medial wall across subjects. This does not change with contrast.
