Hi all,
I am trying to run recon-all on a structural for one of my subjects, but

HI all,
We had submitted a paper based on cortical thickness analysis in Qdec. The
reviewer's had couple concerns regarding the QDec analysis. We would
appreciate your help to address/resolve those issues. Here are the concerns:

Hello freesurfers,
I have an image that is in RAS orientation with the axial primary slice
direction. Is there anyway to change this to LIA orientation with the
coronal primary slice direction? I am assuming mri_convert would work, but
I'm not sure which flags to use.
Thanks in advance.

Dear Doug,
Would you please shine some light on what quantities are being plotted in
those statistical maps of QDEC? Some linear combination of the columns of
the design matrix?
Also, what is the "default" design matrix?
Thank you very much!
Sincerely,
Ye

Hi Luzia
the lh.EC_average should be a symlink to
$FREESURFER_HOME/subjects/lh.EC_average
if it doesn't exist, create it with ln -s

Your original labels are not on fsaverage. You need to transfer them to
fsaverage using mri_label2label. That should fix your first problem. The
2nd should be fixed by having your ctab go from 0 to 58 with 0 being the
unknown label

Dear Doug,
If I only have two groups, does the statistical test reduce to a two-tail
t-test?
Sorry, I meant to ask what the "default" contrast is, meaning what the
contrast is when I specify no nuisance factor?
Is there an official document where the QDEC setup is gone over
systematically?
Than
QDEC creates a sentence that describes each contrast. Is that sentence
not clear? I think the only other docs we have for QDEC are the tutorial.

Dear FreeSurfers,
1. Can I expect recon-all to work on a T1W image where only part of the
brain is in FOV? The obvious answer is that I should just try, but it would
help to know in case I get unexpected results. Perhaps a more appropriate
question is: what should
