Re: [Freesurfer] ERROR: comparison in expression (FS with SGE)
by Xue, Feng 19 May '12

Sorry, I didn't notice that the reply address was not the list, I've done re-post it. Is there any method to check whether it is ok? For SGE, it might only write errors to dot e files instead of warnings. It seemed like a shell syntax error, however, I don't have that experience to check the recon-all script.

Hi Fred, yu probably checked the following already, but on the off chance you have not... Maybe you have set X11 to 256 color mode? Start X11.app (from /Applications/Utilities) go to the X11 menu, select Preferences..., switch to the tab called output and see what is selected for Colors. If it is set to 256 Colors you have your root cause, just switch to something higher and all should be fine. best Sebastian On May 9, 2010, at 9:00 AM, freesurfer-request(a)nmr.mgh.harvard.edu wrote: > Send Freesurfer mailing list submissions to > freesurfer(a)nmr.mgh.harvard.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer > or, via email, send a message with subject or body 'help' to > freesurfer-request(a)nmr.mgh.harvard.edu > > You can reach the person managing the list at > freesurfer-owner(a)nmr.mgh.harvard.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Freesurfer digest..." > > > Today's Topics: > > 1. tksurfer/tkmedit display color fix in OSX 10.6?

downsampling 4D volume
by ythomas 10 Jan '12

10 Jan '12

Hi, I am trying to downsample a 4D volume using mri_convert. However, it seems to be killing the 4 dimension. For example, if I do mri_convert -voxsize 4 4 4 tmp.mgz tmp444.mgz The original volume which is 256 x 256 x 256 x 120 becomes 64 x 64 x 64. Thanks, Thomas

Hi David, I'm surprised you didn't have to do this in the past. We always space our jobs out.

Re: [Freesurfer] Longitudinal processing
by Martin Reuter 27 Oct '10

27 Oct '10

Hi Sandra, (and the list, I think this might be interesting for others) 1. the longitudinal ?h.thickness files are in registration (within subject) so in order to compute the difference or the rate you can simply use: mris_calc -o lh.outdiff sdir2/surf/lh.thickness sdir1/surf/lh.thickness and for the rate, you can divide by time 1 thickness or by the average thickness. If the time points are not equally spaced across subjects, you can also divide by difference in time. It is best to smooth the thickness files before you do all this (i.e. within time point smooth the ?h.thickness files with mri_surf2surf). 2. then map everything to your template (e.g. fsaverage) with mri_surf2surf 3. there you can stack the thick-differences or thick-rates with mri_concat 4. do the glm Beste Gruesse, Martin On Tue, 2010-06-29 at 21:50 +0200, Sandra Duezel wrote: > Hi Martin > > I just have got your answer to the longitudinal processing question > from Michele and have some other questions regarding the output data > from the longitudinal stream. > Our study contains MRI scans of 45 elderly subjects from 2 timepoints. > I have done all steps from the longitudinal stream and it worked > without any problems. > > Now I would like calculate the thickness difference maps between the > prae and post scans, which are already longitudinally processed. > > I have tried the thickdiffmap-script using the <tp1>.long and > <tp2>.long data.

Mapping labels to the RH on Macs
by Tessa Harrison 14 Oct '10

14 Oct '10

Dear FreeSurfers, I am running FS 4.5 or FS 5.0 on Mac OS X 10.6.4 -Intel (see attached screenshot). I am not able to map RH labels created in fsaverage to the RH of any of my subjects. LH labels map to the LH from qdec "Map Label to All Subjects" option and from the command line with no problem. However, when I try to map RH labels (that map correctly to the RH in fsaverage) to individual subjects, the command appears to work (no error messages), but something goes wrong. It appears that the label is actually mapped to the LH because when I pull it up on the RH in an individual subject it looks like scattered dots (see attached image). The same thing happens on another Mac in our lab. I have tried both FS 4.5 and 5.0 and the problem occurs in both versions. Could this be a bug in the Mac FS release? I did not find any mention of this problem in the archives. Thank you for you help! -Tessa

QDEC 5.0 with data from 4.x recon-all data
by Mira Michelle Raman 04 Oct '10

04 Oct '10

Hi, I was wondering if it were possible/advisable to use data processed and cached using earlier versions of FreeSurfe with the new 5.0 QDEC, since it has enhanced capabilities.
