How did you do the 5.3 analysis? in 1mm/conformed space? And what are you hoping to accomplish by running it in v7.1 with -hires?

Hi Everyone,

I have access to two large datasets (~600 scans) that were previously collected, processed, QC'd, and manually edited where necessary in Freesurfer 5.3 with recon-all. However, the data is 0.9 mm isotropic collected in a 3T scanner. I am attempting to decide if the cost/benefit is worth switching the pipeline to Freesurfer 7.1 with the -hires flag? The processing time is not the issue, mainly redoing QC and manual corrections is the concern.

1. To publish 0.9 isotropic is it necessary to use the -hires pipeline?
2. Is it appropriate to apply corrections calculated in the Freesurfer 5.3 standard pipeline to Freesurfer 7.1 -hires (and double check). Or do the manual QCs need to be completed from the ground up?
3. With the other 2 questions in mind, is it better to just go ahead and convert the data to Freesurfer 7.1 -hires?

Thank you, Daniel
