Hello,
When FS5 came out, I copied over my FS4 reconstructions to my FS5 Subjects Directory, and then reran them using the FS5 recon-all stream. This updated their subject folders with the FS5 changes, but not in as many places as I would have thought. For example, on 6 test subjects, I created their FS5 folders from FS4 folders that I copied over and then ran the FS5 recon-all stream. I also created another copy of their FS5 folders from scratch. The average difference in their ICV values was -12,000 mm^3. Is it to be expected that FS5 reconstructions running on FS4 folders will not include all possible improvements? If I want to get an accurate an ICV measurement as possible, is it advisable to rerun all of my subjects in FS5, starting from scratch?
As always, thank you for your valuable assistance! Jeff Sadino
