updated mri_convert file
by Olivia Cheung 28 Jun '16

28 Jun '16

Hi Freesurfer team, I would like to download a copy of the updated mri_convert but the link <https://surfer.nmr.mgh.harvard.edu/fswiki/ReleaseNotes> on the Release Notes webpage does not seem to work. Would you please fix that? I need the updated mri_convert because I'm getting the following error: "nifti1Read(): unsupported slice timing pattern 5" Thanks! Olivia

Hello Freesurfers, Where can I find the documentation about how is the retinotopic analysis performed in Freesurfer? Thanks.

Freesurfer/Freeview help
by Abbie McNulty 27 Jun '16

27 Jun '16

Hello, I am trying to segment a MRI brain in order to create a mesh of the image into finite elements, but I am very new with Freesurfer/Freeview and am not familiar with the tools. So far, I have only uploaded brain.mgt from the bert file that comes with the program. If I wanted to mesh this brain, how should I proceed? The online tutorials have confused me especially since I am not sure if I am supposed to be using the terminal or the command window for a lot of the code commands. Any help would be appreciated. Thanks! Abbie McNulty -- Abigail C. McNulty Stanford University Class of 2018 B.A. Candidate in Bioengineering Stanford Women's XC/ Track and Field

Stuck on “CORRECTING DEFECT”
by Dan Loewenherz 27 Jun '16

27 Jun '16

Hi freeserver folks, First time poster here. First off, thanks so much to the folks who work on and make this software available to the public. It seems like pretty incredible tech, from what little I understand of it. :) My problem is that the freesurfer process appears to be stuck on the recon-all command. It’s been sitting at ”CORRECTING DEFECT 0 (vertices=96285, convex hull=13916)” for about 10 hours now. Any way to cut that number down or should I just let it keep doing its thing? I’ve pasted all of the output pasted at end of the message. Thanks so much!

Freeview nightly / dev / beta
by Vincent Koppelmans 27 Jun '16

27 Jun '16

Hello Freesurfer developers, I am looking for a version of Freeview that recognizes the -noquit flag. V 1.0 Build Aug 24 2015 14:50:08 allows this, but is no longer available from "ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev <ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/dev>”. I am particularly interested in a Linux version. Would it be possible to open up access to the beta versions of Freeview to us endusers again? Thanks! - Vincent

License for data file?
by Matthew Brett 24 Jun '16

24 Jun '16

Hi, Over at our nibabel Python package, we've got stuck trying to work out what license we should give to a file we got from Freesurfer version 3.0.3: https://github.com/nipy/nibabel/pull/461 The file is `subjects/bert/surf/lh.inflated.nofix` from Freesurfer 3.0.3. It looks like this is a modified version of the original files from the tutorial dataset - which I think derive from here: https://web.archive.org/web/20070711224104/http://www.fmridc.org/f/fmridc/7… Is that right? What license should we give when we are distributing the `subjects/bert/surf/lh.inflated.nofix` in an archive we are using to test our software? Thanks a lot, Matthew
