[Freesurfer] Cortical thickness difference measurement
Hello again! Firstly, let me thank you for your precious previous advices, which pointed me in the right direction. I have another question for you: I have read your article on Reliability of MRI cortical thickness measurements and its relation with scanner and field, and I would like to know what function did you use to subtract the subjects' average cortical thickness files in order to have a cortical thickness difference layer. I don't know if this is a very basic question, but I can't seem to find how to do it with FS. Thank you!

Re: [Freesurfer] Cortical thickness difference measurement
Hi Joao, I think we did all the subtractions and such in matlab. There are .m files for reading/writing most of our formats. cheers, Bruce On Thu, 1 Jun 2006, Joao Pereira wrote: Hello again!

[Freesurfer] Using cortical segmentation in an anatomy project
Hello ! I work for the department of Anatomy (http://www.medecine.unige.ch/GRAC/) in the Centre Médical Universitaire of the Université de Genève (http://www.unige.ch/). We're planning to use the FreeSurfer software suite (or more precisely, the surface-based stream ) in a project that aims to synthesize brain models for teaching through rapid-prototyping (like 3D-printing) out of brain MRI, thus by-passing and giving an alternative to using dead human bodies for teaching. I have 2 questions relative to this project : - Does anyone here have recommendations (or references) about MRI sequence parameters to obtain best contrast for optimal segmentation ? Our preliminary test data wasn't top quality indeed, and we're planning to obtain new datasets. Does anyone has some tips to give us ? - The download page mentions that the source code will be soon released (https://surfer.nmr.mgh.harvard.edu/fswiki/Download?action=highlightvalue=source+code), but that we'll have to wait until all non-releasable modules are replaced with open-source-able ones. How far has the OS'ing effort gone until now ? Most specifically, which modules are already OS'able ? And how much effort remain to be done ? When will we see an OS'ed version ? Under what license are those sources going to be released ? (GPL, BSD, other ?) Thank you and have a nice day. - Ivan Topolsky - ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
Re: [Freesurfer] Using cortical segmentation in an anatomy project
Ivan, In response to your first question about sequence parameters for optimal segmentation, we achieve optimal gm/wm segmentation using the MP-RAGE sequence protocol. For info, see Data Requirements section of this page: https://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferBeginnersGuide which should lead you down to this page of parameters used for structural imaging: http://www.nmr.mgh.harvard.edu/~andre/Sequences/SagMPR8Min.html In response to the open-source questions, we are at least six weeks away from finally releasing the open source code. The license it will follow is this: https://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferOpenSourceLicense Nick On Thu, 2006-06-01 at 16:46 +0200, Ivan Blagoev Topolsky wrote: Hello !

[Freesurfer] error in 'create surface'
Hi all, I posted a question, but for some reason, I didn't get any response. Please help me on this. Here is the question. I ran 'process volume' and 'create surface' on csurf. The created surface (left inflated) has brain stem attached to it. So, I editted 'wm' slices to get rid of it, and ran 'create surface' again. No change took place. I tried commandline 'recon-all -stage1 -subjid ID', with no luck. Would someone suggest any comment on this?

Re: [Freesurfer] error in 'create surface'
Nam, The csurf application is no longer supported (and has been removed from the newest release). The recon-all script now performs all processing stages, where the three main stages are -autorecon1, -autorecon2 and - autorecon3 (-stage1 is a deprecated option). You may want to see our new tutorial, here: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial to learn what sorts of problems can occur during the various stages. It's hard to say from your email what the problem may be, but it could be a bad Talairach alignment. The tutorial discusses this. Note: you should not see the brain stem after the image has been skull-stripped (which occurs during the -autorecon1 stage).

Re: [Freesurfer] eTIV bug
Sasha, The eTIV bug (fixed in v3.0.2) affects mri_label_volume and mri_segstats. mri_segstats is run as part of the standard recon-all stream, and incorporates the eTIV calculation, putting the results in the file subjid/stats/aseg.stats, the lines beginning with: # Measure . So you would need to rerun mri_segstats using a newer version. If you prefer, I could send you the binary for your installation (rather than re-install all of freesurfer).

[Freesurfer] How to disable jumping tool windows? Environment variables?
Folks: Both tkmedit and tksurfer have tool windows which jump to a location below their respective main image windows whenever the image windows are moved or adjusted. This prevents the image windows from being enlarged to full screen height, because the tool windows then jump to bottom of screen, and behind the main window. Is there some way to signal these two apps not to move the tool windows? Also, if there is such a setting I'm suspecting it would be an environment variable. I looked at the Wiki, but didn't find a listing of useful environment variables -- is there one to be had?
