Problem with recon-all - nu_currect
by Andrea Tateo 02 Jun '13

02 Jun '13

Dear FS experts, I have a problem with the command "recon-all". In many cases when I use it on the same brain's MRI, on the CLUSTER COMPUTING INFRASTRUCTURE, about 40% of my jobs finish without erros while the other are killed at the command "nu_currect", as you can see from the file.log in attachment. Do you have any suggestions? Thanks a lot for your help. Best regardes, Andrea

REPOST: NFS v4 on CentOS 5.4 or Red Hat 6.2
by Garikoitz Lerma-Usabiaga 01 Jun '13

Hi, Has anybody got problems using FS with NFS v4? We cannot write subjects if the SUBJECTS_DIR is in a NFS v4 system. Many thanks, Gari ---------- Forwarded message ---------- From: Garikoitz Lerma-Usabiaga <garikoitz(a)gmail.com> Date: Tue, May 7, 2013 at 5:25 PM Subject: NFS v4 on CentOS 5.4 or Red Hat 6.2 To: Freesurfer <freesurfer(a)nmr.mgh.harvard.edu> Hi FS experts, we have changed our file systems to NFS v4 and we found that FS cannot write to it (I mean, FS installed in an app server and subjects in the file system is not working). Last new I have is that FS in CentOS could read but not write and in Red Hat could not write or read. Is it a known problem? Is it something going on with FS or the problem is in our end? (the rest of the programs are working fine: FSL, Matlab...) Many thanks, Gari

CVS crashing consistently: update
by Graham Wideman 31 May '13

31 May '13

Hi MGH folks, Update to previous report: Review: Both of my attempts from scratch to CVS the 5.3.0 source failed after about 760 files, directory trctrain. CVS quit with fatal signal 9 error. Previously when I tried to restart either of these, CVS would quickly run through all the up-to-date directories, then hang at trctrain, with no terminal, disk or network activity (as judged by router lights). I have since let it sit there for probably 20 minutes, and suddenly the process came to life... downloading trctraindata.tar.gz (over 500 Meg). So, I don't know if or why that large file was resulting in signal 9 error, but progress is now unjammed. -- Graham

CVS crashing consistently
by Graham Wideman 31 May '13

31 May '13

Hi MGH folks, I am attempting to download the source via CVS as described here: http://freesurfer.net/fswiki/ReadOnlyCVS using: cvs -d :pserver:anonymous@fsvm.nmr.mgh.harvard.edu:/usr/fscvsroot checkout -P -r release_5_3_0 dev (ie: 5.3.0 source) The CVS process is consistently stopping about 760 files into the process, with the final lines of output being: ------------------------------------------------ cvs checkout: Updating dev/distribution/trctrain U dev/distribution/trctrain/Makefile.am Terminated with fatal signal 9 ------------------------------------------------ After the first attempt got stuck here, I attempted to run the checkout command again. CVS quickly displays a bunch of "Updating xxxxx" where xxxxx is all the directories already downloaded, then gets to trctrain and stops indefinitely. (I then killed it using Ctl-C) I then created a new local directory and restarted from scratch. The checkout proceeded apace, and then got stuck at the same place (trctrain), with same failure message. So... I'm thinking it might be something at your end, maybe disk problems in whatever files come next after the last one above? FWIW, I'm using cvs as installed with Mint 15, which is 1.12.13-MirDebian-9 (client/server) -- Graham

Re: [Freesurfer] mprage flag in recon-all
by Caspar M. Schwiedrzik 31 May '13

yes, but recon-all just calls mri_segment with -mprage and mri_normalize with -mprage. I would like to know what -mprage does in these two functions, but i cannot search them because they are executables, not scripts.

Difference between Original and Main surfaces?

Always wondered, was never quite sure. I'm wondering why sometimes they mirror each other and other times they shift away. jon

Group Analysis
by Fotiadis, Panagiotis 31 May '13

31 May '13

Hey Doug, Sorry for the overwhelming amount of questions. I wanted to confirm something. Suppose you want to do group analysis between two groups say a healthy cohort vs a diseased cohort. Each cohort has ~40 and ~30 subjects each (different people), and you want to compare how for instance the cortical thickness decreases over age in the one group versus the other. Do you still set the contrast vector as [0 0 1 -1] ([intercept 1 intercept 2 slope 1 slope 2]) and follow the analysis described in https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/GroupAnalysis or do you go on a different way since there are different subjects instead of one with 40 (or 30) different longitudinal data for each cohort? Don't we need to correct the age slopes for the fact that we have 40 (and 30) different subjects in each cohort? Thanks, Panos

ventral DC
by Yang, Daniel 31 May '13

31 May '13

Dear all, in the aseg.volume, there is a term called 'ventral DC' and I am wondering what it is. I looked up the previous posts and know DC = diencephalon, and it's a grab bag of stuff that cannot be resolved. However, does anyone know what exactly ventral DC is? Thanks!
