[Freesurfer] Processing after edits.

2008-08-14 Thread Matt Clarkson
Hi there, If you run recon-all, and then do some edits, for example control points, then the tutorial says you do: recon-all -autorecon2-cp -autorecon3 -subjid subject4_before Similarly for white matter: recon-all -autorecon2-wm -autorecon3 -subjid 111_manual_edits_before and similarly for br

I think at least part (1) of Eliezer's list is possible with the existing content on the FS wiki. Specifically, now that the wiki is using MoinMoin v1.6 it is possible to export pages as latex (see http://moinmo.in/FormatterMarket for the formatter plugin) which would be a very fast way to put

Hi all, I need data which are in the aseg.stats file (which is in the stats file). Some patients haven't the aseg.stats file in the stats file, so does somebody know where I can find the aseg.stats file? Thanks Irene Mattisi Multiple Sclerosis Centre of Padova, Italy ___

I agree. We have out hands full writing unit/system tests, developing new algorithms and tracking down bugs. We try to keep the docs up to date, but it's pretty hard to do. If people were willing to contribute short pieces of documentation for different tools that they are familiar with, we can

Dear List, I am testing within qdec an analysis of the subcortical volumes and using for this the subjects of the buckner_data.( First of all i am not sure it this is already implemented within freesurfer - in the Design card it says something like 'Volume-Based not yet implemented' ) Well, i

2008-08-14 Thread Nick Schmansky
Thomas, The term 'volume' can get a little confusing. As you noticed, volume- based analysis is not yet implemented in qdec. What this will be is to take a freesurfer volume measure, like hippocampal volume, and use that as the independent variable to regress against, say, age. The output would

It is a defect of some kind. Use the save point / goto feature of tksurfer and tkmedit, as described in the tutorial, to see discover the cause of the defect. That is, click on a point on that needle in tksurfer, click save point, then click goto point in tkmedit, after loading the brainmask and

actually I wouldn't worry about it. It's not cortical. Might be the optic radiation, but it will have no effect on anything you want to do. If you don't like the way it looks you could erase the wm voxels that make it up, but I wouldn't bother. On Thu, 14 Aug 2008, Nick Schmansky wrote: It i
