Hi all,
I am starting with qdec and i have a simple question. I have 30 recon-all
subjects but I didn't do the -qcache option.
1- I want to know if I need to run this -qcache option even if I use the
fsaverage target subject, or this is only necessary if se my own average
subject?
2- Where do I
Jose.
1) Yes. You should run -qcache
2) Yes. This file is used to describe your experiment. You can have more
details in the FreeSurfer tutorial for group analysis.

Hi there,
I have a question regarding the longitudinal processing stream in the new
release. I've already analyzed my data at different time points using the
cross-sectional processing stream using the previous version of
freesurfer, and would like to know if this is the same as doing so with

Hi Bruce-
Agreed. Visual check of talairach looks good and manual correction of slight
sagital angle fails to improve z value, hence the current notal-check.
Looking at recon-all.log, there is a statement that The surface validation has
detected a possible Error", with a suggestion to use the '
Did you check the skull strip? You can send it to us if you want and
we will take a look.

It is a bad skull strip. I am increasing watershed param and will try

Hi all,
I have run the same image twice with recon-all and gotten different
results for the cortical parcellation, with regions of the cortex
differing an average of 2% in volume and the biggest difference being
11% (left bankssts). This is on a healthy, elderly brain. I'd like
to try runnin
Dana,
I believe you can achieve this by running recon-all on the subjects with
the -norandomness flag. Unless you are using a version of FreeSurfer that
is older than v3.0.4 - let me know if you are.

Hi all,
I have a couple images that have poor gray-white boundaries, and the
cortical parcellation did not come out well. Is there any way to
manipulate thresholds to try to enhance the gray-white segmentation?
Thanks,
