Agreed. A validated protocol run on a very large group of subjects in 5.3 was attempted with similar data in 6.0 and not only was the longitudinal edit stream nearly non-functional for white matter edits, cross edit performance was disappointing. I am currently waiting on a response to these po

In my experience, OSX has weird issues with things in system and Application directories. My guess would be your files have inherited some permission flags from the Linux environment and OSX is having trouble making them properly available. The first thing I would try would be to copy them to a

Hello, I have worked quite a bit in the past with fs 5.3 on datasets which required a fair number of manual edits to the white matter volume in order to correct defects in the white matter surface. Typically, these edits take the form of removing voxels in the wm.mgz volume that have been incorr
