External Email - Use Caution Dear Eugenio,
Thank you very much for your prompt reply. This has clarified things for us. Best wishes, Vanessa From: <freesurfer-boun...@nmr.mgh.harvard.edu> on behalf of "Iglesias Gonzalez, Juan E." <jiglesiasgonza...@mgh.harvard.edu> Reply-To: Freesurfer support list <freesurfer@nmr.mgh.harvard.edu> Date: Wednesday, 20 May 2020 at 10:44 PM To: Freesurfer support list <freesurfer@nmr.mgh.harvard.edu> Subject: Re: [Freesurfer] Freesurfer version 7.0.0 and hippocampal segmentation Dear Vanessa, 1. No changes were made in the hippocampal module between 7.0 and 7.1, so you don’t need to rerun (as the subjects were reconned-all with 6.0, which doesn’t have any problems). 2. Yeah it may not be as easy to reproduce as running everything with the same version, but it’s perfectly fine to write in your paper that you reconned the brains with 6.0 and then processed the hippo and amygdala with 7.1. People (even reviewers!) understand that some labs don’t have the CPU cycles to quickly rerun all their data with FS every time a new version comes out.

We have processed a large dataset using freesurfer version 6, with all subjects being processed (recon-all) with the same version/platform. We would now like to segment the hippocampal subfields using the enhanced version of the module as outlined here: https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields<https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields> which requires Freesurfer 7. We have successfully run the hippocampal segmentation using freesurfer_v7.0.0_dev_20200405 (7.1 was not available at the time). My questions: 1. Given the recall of v7.0.0, does this mean that we should re-do the hippocampal segmentation that used v7.0.0 with v7.1.0? In other words, are all functions within v7.0.0 to be avoided, or just the recon-all stream? 2. Given that the recon-all was processed with v6, is it ok to perform the hippocampal subfield segmentation with v7? I understand that it is fine to perform post-processing functions outside the recon-all stream with newer versions (provided recon-all was done with the same version). Is my understanding correct? Thank you for your assistance. - Vanessa
