Freeview crashes xterm
by Venkataraman, Archana 03 Mar '14

03 Mar '14

Hi, I am running freesurfer on a RedHat v6.5 machine (Santiago). I think the installation was successful and the paths are set correctly. However, my xterm crashes when I try to launch freeview. Strangely, the program works as expected when launched remotely via NX. Has anyone encountered this problem before? Thanks. - Archana

Re: [Freesurfer] Problematic dilated ventricles

Dear Bruce, A few weeks ago you made code mods to mri_em_register and got recon-all to process a subject of mine, MPS1036-1. You sent me the new aseg.auto_noCCseg.mgz and told me to run recon-all -make all -s MPS1036-1. I did this but I get the message make: Nothing to be done for 'all' and when I visualize the segmentation with tkmedit, there appears to be no change to the pial or wm surfaces. Could you please advise? Thank you.

But there are the csd files as I run simulation with --bg option. Also I try to find the csd files in the first contrast directory, but I think, maybe I am wrong, none of these is csd files that you suggest.

Hello, I want to define a new label in aparc+aseg.mgz (to mark certain brainstem structures); I would appreciate it if you help me with how I have to do it.

aligning/quality of CT
by Borzello, Mia 02 Mar '14

02 Mar '14

Hi Freesurfers, In general when aligning an MR and a CT, is a 32 slices CT sufficient? I've done a coregistration and am looking at it in tkmedit and the quality of the image isn't so good. Thanks, Mia

Re: [Freesurfer] longitudinal process

Hi Anna, No, you can still use links. When rerunning the base, the cross are not changed. Once the base loiks good, you also have to rerun the longs of course.

May I ask other question; after editing the base it says to reocnstruct with recon-all -base -tp1 -tp2 etc. Does this require that all scans are located in the same directory? (Before i used symbolic links as scans are in different directories) but i am unsure whether after editing the abse anything further is actually done to the cross runs? Thank you for your help, Anna On Tue, Feb 18, 2014 at 7:58 PM, Martin Reuter <mreuter(a)nmr.mgh.harvard.edu> wrote: Hi Anna, the linear mixed effects models can include subjects with a single time point and it would be a shame to drop that information. That is why we modified the longitudinal pipeline (use 5.3) to allow processing of subjects with a single time point. However, it is necessary that these images undergo the same processing steps as the rest of the data (to avoid bias). So you run it exactly as other subjects, with a cross sectional, -base and a -long step: recon-all -all -s <tp1id> -i path_to_tp1_dcm recon-all -base <templateid> -tp <tp1id> -all recon-all -long <tp1id> <templateid> -all Best, Martin On 02/18/2014 04:58 AM, Anna Jonsson wrote: Dear Freesurfer experts, I want to know if possible when doing longitudinal stream to put subjects with only one time-point through the processing (eg base and long runs) in order to subsequently use with the Matlab lme tools?

Dear Freesurfer experts, I want to know if possible when doing longitudinal stream to put subjects with only one time-point through the processing (eg base and long runs) in order to subsequently use with the Matlab lme tools?
