Hello, I am running the longitudinal processing using version 4.5 and was wondering if there are any data quality checks specific to the longitudinal stream (other than the standard ones listed for the cross-sectional analysis)? For example, is there a way to check the registration between TP1 & TP2 when creating the base?
Also, in two of my 36 subjects (one in creating the base, one TP->base longitudinal processing), the final step that creates wmparc.mgz was taking extremely long to finish (I let it go 18hrs before killing the process, and only 25 slices were complete). After looking at the aparc+aseg.mgz file, I noticed that part of the right hemi, and all voxels outside of the brain received a value of 41, corresponding to right cerebral white matter. The aseg.mgz appears to be fine, and the pial & inflated + annotation file appeared OK in tksurfer. Any ideas on what may be going wrong with these cases? Thanks! -Ryan _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
