Hi Robert
I'm really sorry to hear it. I suspect that though that you would be better off rerunning everything through 5.3. It should be the case that all manual edits are retained and it's just compute time that you will have wasted. 5.2 had a user-requested mod that made the surfaces inaccurate in some acquisitions, although not in our test suite, which of course is why we didn't catch it. We have announced the problem with 5.2 so I would worry that if you try to publish with it you will get yelled at by some reviewer.
Again, I'm sorry for the wasted time. We try hard to avoid this kind of problem, but our resources are quite finite and there's only so much testing we can do (and in this case, 5.2 passed all our internal tests).

Hi Bruce and others,
We started a rather extensive push of data through the linux 5.2 release of free surfer. We also use OS X at times and I was hoping to get a R5.2 for MAC but I see it's not available. One of the guys that works in my lab — Jon Holt — also said that 5.2 was no longer available and indicated he heard there may be issues with 5.2
So two questions:
- we have > 100 subjects pushed through R5.2 and still working inside 5.2,
are we in trouble? What's the advice. We have many FTE hours on the editing and would be very painful to go back (we already did with with 5.0 to 5.2 change).
- are we safe using 5.3 in conjunction with 5.2?
Any other advice about versions etc. Given the amount of time it takes to push data through it is difficult to keep changing versions, plus from a publication view it would be a hard sale I think to reviewers to indicate we used multiple versions.
Thanks,
-Robert
