We haven't been able to get FS 5.3 (running on a linux server) output to display on our Win 7 PC's using Xming or Exceed X11 emulators. We get errors (below) on all our PCs. Appears to be related to low-end video cards not-supporting openGL.

Why would you want to do that?

I have successfully processed data with FS v5.3 (linux/CentOS) using recon-all -all.

Is it possible to make modifications to the 5.3-generated brainmask.mgz (primarily dura removal) and wm.mgz files using a much older 4.4 version of FS and then re-run recon-all on 5.3 with these modified files. I'd also be generating control points (control.dat file) on 4.4 as well.

In other works are there file formatting differences between these FS versions for just these 3 files that could pose a problem when re-running the dataset.
