Hi everybody, We have a set of patients who were all run using the same freesurfer version, except that some of the patients had their dicom files converted to 001.mgz with a somewhat older version of freesurfer. For example some of them went through that step with version 4.0 or 4.0.2 or 4.0.5 etc. Anyway, I was wondering, is there any reason why those 001.mgz files would not be usable?
