Hi,

I was wondering if you could help me or give me more information. I have 
pre-processed my MRI data using FreeSurfer version 7.0, which has been 
recalled. I used the same version for the thalamic segmentation. I have 
elaborated my data one year ago. Do I have to pre-process all my data again? I 
randomly segmented few subjects with versions 6.0 and 7.2 and I implemented a 
visual quality check but it seems to me that the images segmented with version 
7.0 are good. I runned also t-tests between the extracted cortical volumes of 
the three versions and there are overall few differences across the versions. 
Where could I see if my data are not good? Which are the effects of the bug in 
version 7.0?
