Hi all,
I receive the error: ERROR: MRISread: cannot read surface data from file ./long/surf/lh.thickness.fsaverage.S1-S3.mgh!
when I run mri_glmfit with the command: mri_glmfit --glmdir long/g1v0 --surf long lh thickness.fsaverage.S1-S3.mgh --fsgd long/S1-S3.fsgd --osgm
I am working on mri_glmfit for a one sample ttest of the thickness of multiple patients, all qcached to fsaverage. I ran the reconstruction and then ran -qcache for each subject. I then used mri_calc to find the difference in thicknesses of Session 1 and 3 for each patient (in fsaverage) and concatenated with mri_concat for the glm. But when I run the glm, it gives me the above error. How would I fix this?
Also, I am wondering if there is a way to register the right hemisphere to the left hemisphere, since we are working with stroke patients and would like to compare all the contralesional hemispheres. Thank you!
