Hello,
We would like to calculate a Total Brain Volume based on data in aseg.stat
generated from version 5.1.0. Can I use intra crainal volume as estimated for
total brain volume? Or should I just add total grey volume with subcortical
grey volume with total white matter volume?
Thanks,
Knu
Dear freesurfers,
I have a simple question concerning the freesurfer 5.1 FSFAST preprocessing. In
the preprocessing the functional images are registered to the anatomical ones
using bbregister. This is the 3rd in a series of 8 preprocessing steps. If the
preproc-sess registration fails it is po

Hi,
many thanks for your help!
Unfortunately, I still have some questions:
1) Why would someone only want to display the results on a cohort-specific
average, but not use that average for calculation?
2) So if I want to use my cohort-specific average for calcuation of the
cortical thickness
THAT was the problem. Thanks so much Bruce.
I owe you one.

Hi Michael
a couple of typos. It should be "make_average_subject" (note no "s"), and
it should be --subjects (note the ending "s"). I also don't see a flag
named --no-aseg, which I think is why it's being included as a subject.
What are you trying to do?

Hi Christina,
1. Displaying data on your own subjects average can be less misleading than
on our's, particularly if you don't have many subjects. It shows at least
one measure of the true variability/accuracy of the registration of your
subjects.
2. To make a study-specific target for the sphe

For #2, make_average_subject will create the .tif file in the output

They rely on the registration. What is failing? It is usually the
initialization that fails. If you're using FSL, you can try using the
SPM registration (though it's a little trickier to set up).

Hi everyone,
What is the best way to concatenate transforms (register.dat files, .lta files,
etc.)? I'm interested in registering functional data to a structural in
another session using a functional to in-session anatomical registration
combined with a in-session anatomical to out-of-session
Why not just register the functional to the desired structural directly?
That will work better than concatenation I think.

Dear Freesurfers,
I had a question about interpreting the results of the Monte-Carlo
simulation. It is my understanding that the clusters are labeled based on the
value of the maximum significant vertex in a cluster. So, assuming that a
cluster kind of borders or extends over 2 adjacent
That is correct and expected. The only constant is the vox2vox
transformation. Once you change the vox2ras (eg, scanner or TKReg), then
it must change the ras2ras transform in order to keep the vox2vox constant.

Dear all,
I have heard that the FWE correction sometimes could be demanding and kill

Thanks Doug for the response. Yes, I do understand that there is going to be

Generally, reviews and editors will not let you publish without

Dear Doug,
indeed the initialization fails. I was able to initiate bbregister manually,
giving a good registration result. Can you give me a hint how to
modify the registration and keeping the preproc-sess stream intact?

You can try running register-sess outside of preproc-sess, something like
register-sess -s session -fsd bold -per-run -init-spm
before you do that, you need to have spm5 and matlab, and change your
matlab/startup.m to add the spm5 path
path(path,'/usr/pubsw/common/spm/spm5');

so it seems that i ran make_average_volume which does have a --no-aseg flag
make_average_subject really just runs 2 other commands
make_average_surface and make_average_volume.
bruce the reason i did this is that mike was running a `super` average, i.e.

FYI when the --no-aseg option is used with make_average_subject, it gets

Hello,
I'm running bedpostx_seychelles from the seychelles prompt (via trac-all

Hi Sean,
You should look at the Exit_status. If it is '0', then your job ran
successfully. If it is '1' or something else, then there is an error. So
it looks like your job ran correctly.

Hi, Douglas
I have uploaded the file to the system.
Also, my new results showed that when ic3.tri (instead of ic2.tri) is used as
the input, one ROI at the similar location is also missing. Hope it will help
you diagnose.
Thanks

Hi Priti,
Thanks, but would seem that despite the 0 status, something didn't run
correctly. trac-all -path cannot find the file merged_ph1samples.nii.gz.
Actually none of expected bedpostx files, other than nodif_brain_mask have
been created in the dmri.bedpostx folder.

Do not run your jobs on seychelles. Most nodes are still CentOS4 and I
think a lot of the tools are simply not going to run on CentOS4 anymore.
Run them on launchpad and if you still get errors then we need to investigate.
