Re: Re: [Freesurfer] error in 'create surface'

Thanks, Nick, If I install a new version of FS, would it be too much of hassle? Because I am in the middle of data analysis for a project using the old version, and I remember I had a big trouble installing different libraries for Freesurfer for the old version, which was a daunting job. Nam. >>> Nick Schmansky <nicks(a)nmr.mgh.harvard.edu> 06/06/01 오후 2:54 >>> 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).

eTIV bug
by Sasha Wolosin 01 Jun '06

01 Jun '06

Dear all, I have processed all my data using Stable v3.0.1. Does the eTIV bug effect any other volume measures? If I want to compute eTIV for my data, should I install the lates version and re-run mri_label_volume -eTIV ?

error in 'create surface'
by Joongnam Yang 01 Jun '06

01 Jun '06

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? Nam.

Using cortical segmentation in an anatomy project
by Ivan Blagoev Topolsky 01 Jun '06

01 Jun '06

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=highlight&value=s…) 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 -

Cortical thickness difference measurement
by Joao Pereira 01 Jun '06

01 Jun '06

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! Joao Pereira

question about flattening surfaces
by adam walczak 31 May '06

31 May '06

Hello, I was searching through the wiki and ran across a page that said to use csurf to make full surface cuts in order to ultimately create flattened surfaces. But while perusing the support archives, it was said that csurf is no longer supported. Is this true? How then do you make the full surface cuts needed to create the flattened surfaces? Thanks Adam adam __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

mghWrite failure in mri_remove_neck
by Graham Wideman 30 May '06

30 May '06

Folks: In our first attempt at a complete run of recon-all, we hit this odd failure: recon-all stopped after the mri_remove_neck stage, claiming that: 1. mri_remove_neck couldn't mghWrite to nu_noneck.mgz 2. But then appeared to perform the neck removal anyway and write the output 3. But then the subsequent step: mri_em_register failed saying that it can't read nu_noneck.mgz ... and sure enough, there is no such file there. The recon-all.log for these steps is copied below. This doesn't appear to be a permissions problem, as the script happily wrote other files to the same mri directory. I do wonder whether mri_remove_neck was actually using the correct directory (we are not using the default SUBJECTS_DIR), but the logic for that is in an executable that I don't think we have source for? But the primary troubleshooting question is why the mghWrite failed, but processing continued anyway, with the subsequent "writing output" message suggesting success of this step (but no file to show for it). Clues?
