Measuring longitudinal changes in brain volume using SynthSeg
by Marco Ganzetti 01 Jul '25

01 Jul '25

External Email - Use Caution Does SynthSeg offer any functionality for estimating longitudinal changes in segmented brain volumes beyond simply subtracting values from two time points? Marco

External Email - Use Caution We usually do not recommend using development builds instead of officially released builds with numbers, e.g., 8.0.0, because development builds can be unstable and may not entirely work - or work the same way - depending upon the day you happen to download a dev build.  However If you can try the latest development build from under,https://secure-web.cisco.com/1jq3XGGcHpTiWr_hdA87MKZEwqIqc5TaHaDuWhZ4… … which will echo a July 01 identifier (20250701) when you source the freesurfer environment,freesurfer-<os_arch>-dev-20250701-f62f34b … then that would help us to look at making a fix on top of the most recent code changes if your issue persists in that current dev build. - R.

External Email - Use Caution Hi, To clarify, I also tried a development build around the end of May when I first posted about this issue (freesurfer/dev-20250521-bad34cc). Does the development build that is currently there (dated today) contain an updated fix to this issue? *Ania Holubecki* On Tue, Jul 1, 2025 at 4:49 PM <freesurfer-request(a)nmr.mgh.harvard.edu> wrote: > Send Freesurfer mailing list submissions to > freesurfer(a)nmr.mgh.harvard.edu > > To subscribe or unsubscribe via email, send a message with subject or > body 'help' to > freesurfer-request(a)nmr.mgh.harvard.edu > > You can reach the person managing the list at > freesurfer-owner(a)nmr.mgh.harvard.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Freesurfer digest..." > > Today's Topics: > > 1.
