computer time, right?

That's what I wanted to avoid: reprocess all the data. Am I forced to?

I have elaborated all my data with recon all version 7.0.
I am doubting whether I should elaborate them again with
7.2 or I can simply run the normalisation with 7.2 on the
data preprocessed with 7.0, since you told me that the
problem with version 7.0 is with the normalisation
process. I ran few t-test on the volumes and the thickness
between version 6, 7 and 7.2 and there are few differences
across all the versions. So actually it doesn't seem that
the results of recon all with version 7 are bugged.

Dear Mr. Greve,
thanks so much for your reply! I have been running
t-tests on cortical and subcortical volumes FDR
corrected on 50 subjects to compare versions 6, 7
and 7.2 but I didn't see so much differences. What
should I do? Should I run again recon all with
version 7.2 on all the subjects? Or can I use
version 7.2 for my analysis on data pre-processed
with version 7?
Thanks a lot in advance!
Annalisa

The 7.0.0 release was recalled because the
intensity normalization *sometimes* did the wrong
thing. It would not surprise me if you were not
seeing any of these effects, but I can't guarantee
that it won't happen in your data. If it was
happening, you would see some big differences in
the thickness, and maybe the subcortical volume.
If you have edited your data, you can run version
7.2 on edited 7.0 data and 7.2 will respect and
incorporate your edits.

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?
Thanks!
Annalisa
