The freesurfer 6.X and 7.x release release notes summarize some changes for Freeview (listed below) since version 5 was released in 2013.   If none of the improvements in features/stability are relevant to what you are doing, then I don’t see why you could not revert to the older 5.X software.  But if you run into issues with a now ~10 year old version of Freeview, we may tell you to use the latest 7.4.1 release from June of 2023.

- R.

• New: interface for x virtual frame buffer (fsxvfb). When you run freeview from fsxvfb, no X server is needed. This is good for taking a bunch of pictures when you don't want freeview popping up all the time. Eg, fsxvfb freeview orig.mgz -ss mypic.png —quit

• The filled.mgz can now be edited instead of the wm.mgz. The advantage to this is that filled.mgz is slightly further in the process and it is more intuitive. The filled.mgz is actually a segmentation of the subcortical mass. In Freeview, you can view it in outline mode, meaning that the edges of the segmentations are actually the surface that you are editing. After that, run recon-all with the -autorecon2-wm -autorecon3 options, just as you would if you had edited the wm.mgz.
  • Landmark-based repositioning of surfaces. Did you ever want to just make the surface move through a certain point? You can do that now by creating point sets in freeview.. Create a separate point set for each surface (lh, rh, white, and pial), then save it in subject/surf with a file name repos.$hemi.$surf.json where $hemi is either lh or rh and $surf is either white or pial. Then run recon-all with the -autorecon2-surfonly -autorecon3 options. Note that you can do this interactively inside of FreeView as well; look under Tools->Resposition Surface. If you do it interactively, the surface may be overwritten next time recon-all is re-run, but it gives you a chance to play with the repositioning.
  • freeview - can now load and visualize diffusion orientation distribution function (ODF) data.
  • FreeView changes: surfce path and label editing, surface annotation editing, automatic segmentation assisted by Geodesic Matting algorithm, displaying two time courses at the same time, better support for Mac (petsc error fixed on Mac)

Hi, 

I'm following up on my quick question from this time last week. 

I have several brains that I sent through recon-all using Freesurfer 7. If I wanted to use Freeview on Freesurfer version 5 to do pial/wm/and control point edits, would I be able to do recon-all through Freesurfer 7?  Years ago, someone asked if they could do recon-all in an older version of Freesurfer and edit in a newer GUI. Doug said that was fine. My question is basically the inverse of their problem. I assumed that since Freeview is a GUI, the version used shouldn't have any actual impact on things as long as we returned to version 7 to recon-all. I just want to confirm that my assumption is correct?

The pipeline would be: F7 (recon-all), F5 (edit with freeview), F7 (recon-all for pial/wm/cp's)

Thanks,
Vincent Edwards
