Hi freesurfer experts,
Is there other methods for multiple comparison correction apart from Monte
carlo simulation in Freesurfer?
Thanks!

hi jens,
here is the post - the links were all broken, but i've updated them below.
note that this run was from nov 2013. i would recommend doing a run with
all the current patches installed.

Hi satra,
I have tried to find some posts about the minimum files required to run
recon-all, but I cannot find anything. Could you please try to find the post in
the archives and provide me the link?
Thank you very much!

yes, I already have the FS outputs for all the subjects. Thanks

I think Michele only wants to regenerate the wmparc.mgz, so just running
recon-all with --wmparc and the xopts should work

ok, so should I just re-run the recon-all with the wm option? i.e.
recon-all -all --wmparc-dmax 100

Hi Michele
sorry, I don't think so. You need to run to the end. The good news is
that when we get V6 out you will find it is substantially faster (if you
have a multi-core machine)

Was the dicom anonymized? Also, mosaics are usually fMRI or DTI. Are you
sure this is a high-res anatomical that will be suitable for recon-all?

There are two ways you can do this.
1. Make an expert options file with the contents
mri_aparc2aseg --wmparc-dmax 100
Run run recon-all like
recon-all -s subject -wmparc -expert YourXOptsFile
2. Look in recon-all.log for the mri_aparc2aseg command, cut and paste
it into the terminal, add
--wmpa
Hi Douglas, thanks for your reply. Is there a way to rerun only WM
segmentation with the threshold option, without going through the whole
time-consuming FS pipeline?
Thank you!

Dear FreeSurfer experts,
There are some image processing tools from the MINC toolkit I have been testing
out on some FreeSurfer files, that all require the image to be in MINC format.

perform the conversion in the other di

Dear Freesurfer experts,
I'm not sure how to apply cluster-wise correction for multiple comparisons when
one is not interested in doing group statistics.
For group analysis you concatenate individuals into one file and use mri_glmfit

Hi Gunjan
FreeSurfer has been designed to work as a pipeline. Picking out individual
pieces and running them may or may not work, and certainly won't be as
reliable. I would advise you to run recon-all -all, then you can use the

if you search the archives, there is a post that lists the minimal set of
files needed for running recon-all.

atlases.

yes, that should be fine. It probably reduces sensitivity in some regions,
but given the complexity of the folds I would expect it to average out.
That said, no one has ever done such a study so we really don't know.

Hi Jens
you could estimate it, but it might not be exactly right. There's no way to
know how long it will take to converge as it depends on the details of the
anatomy. If the current output is not verbose enough for you, you can turn
on more output by:
