Hi FreeSurfer team,
We have a couple of subjects that have really poor segmentation and skull-strip
as well, that seem beyond fixing with just control points or WM edits. I'm
wondering if this occurred because of earlier in the stream, there was a bad
talairach transform? I went back to see the

Hi,
I'm wondering if it's okay to run some of the analyses within one study on
v.5.3 and the other hippocampal analyses on 6.0? Or do you recommend us
starting over for the analyses we've already done in 5.3 for that study?
Thank you!

us is "how many subjects do you have?" -- if it's
less than 50, you may want to just rerun v6 on your subjects as it should
preserve the edits -- but it's recommended you still open them up and double

Hi,
I'm having trouble getting any output from the hippocampal subfield analysis
command. I entered in:
quantifyHippocampalSubfields.sh T1 hippo.txt
/path/to/my/subjects/freesurferfolder
I tried both ways of having the environmental variable subjects directory
defined to the freesurfer folder

Hi,
I was wondering if the hippocampal subfields analysis can still run on a lower
resolution T1 scan than 1mm? One of our datasets has T1 scans with these
dimensions: .93 x .93 x 1.3 .
Would it still run on this dataset, if it's not the standard 1mm to begin with?
Thanks!

Hi,
We were wondering if it would be an issue if we used a dataset in which we
included 5 subjects that have a different number of directions (49 directions)
than the rest of the subjects with a standard number (16 directions). Even if
the preprocessing steps work, will it be an issue comparing
subjects
that have 49.
Best,

We calculated the correlation between thickness two different behavioral
