Re: [Freesurfer] ERROR: comparison in expression (FS with SGE)

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

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.

Re: [Freesurfer] Retinotopic mapping of only polar data
by f.leone＠donders.ru.nl 04 Oct '10

04 Oct '10

Hi everyone, Doug: thanks a lot for the reply, that indeed worked, I now have a polar map overlayed on my inflated brain. But something seems to be amiss, because it plots it mainly on the temporal lobe, with nothing on the most dorsal slices, while actually I only scanned the 18 most dorsal (oriented along the occipital-parietal axis), sot here shouldn't be anything in the temporal or inferior frontal lobe. How can this be/where is it going wrong? Moreover, I'm not sure on the format used by the polar map: the scale bar states it ranges from 1.18 to 1.18, but I don't see the sense in that.

Methods for white matter hypointensities measure
by Laluz, Victor 30 Jul '10

30 Jul '10

Hello guys, I am curious as to how white matter hypointensities (on T1 mprage) are measured automatically for the aseg.stats file in FS? A group at UCSF is interested in using this measure for a study and would like to have a nice explanation or citation to describe how it is generated. I have looked through what I think the likely citations would be on the Freesurfer techniques article listing and came up empty. Thanks!

Parallel processing
by Brendan Robert Ansell 14 Jul '10

14 Jul '10

Hi FreeSurfer users, is it possible to run FreeSurfer on parallel processors? We would like to run mri_glmfit-sim in parallel to reduce the run time. Have you any experience running FreeSurfer in parallel, or would it be relatively easy to reconfigure? Any thoughts would be greatly appreciated. Thanks in advance, Brendan Ansell Melbourne University
