thickness map
by Goldman, Aaron (NIH/NIMH) 07 Aug '05

07 Aug '05

Hi, I've been doing thickness analyses with mris_glm, and was wondering how I could create a map simply showing the average thickness of my entire sample (just as a quality check). Thanks, -Aaron- Aaron L. Goldman Post-Bacc IRTA Genes, Cognition and Psychosis Program, NIMH Building 10, Room 3C108 Phone: (301) 435-0944 Email: aarong(a)mail.nih.gov <mailto:aarong@mail.nih.gov>

Hi Brian, I tried the -f flag and got the following. Is there a newer version of anatomical_stats that runs the -f option? mris_anatomical_stats -f ./lh_aff_limbic.txt -l 1000027/label/1000027_lh_aff_limbic.label 1000027 lh pial unknown option -f -----Original Message----- From: Brian T.

Hi when I've loaded the aseg in tkmedit, is it possible to unload it, or do I have to close tkmedit to view a volume without it again? Thanks, Kristine

Hi everybody I have seen this new dev release on freesurfer site. Do you think it is good for me to update my old version ( feb 2004) ? The old version works properly but I don't know if there are new functions in this new release that are important for freesurfer. Thank you very much for your help Max _________________________________________________________________ Personalizza MSN Messenger con sfondi e fotografie! http://www.ilovemessenger.msn.it/

Multiple simultaneous overlays
by Jane Aspell 05 Aug '05

05 Aug '05

hi i need to view several overlays simultaneously (to see where my activation lies relative to retinotopic map overlays) on a surface. is there no way of doing this with freesurfer? its seems like a function that a lot of users would need. in one posting regarding this you suggested loading the overlays into matlab using load_wfile, combine them, then write them out using write_wfile...are these actual programs? where would i get them from and do i need any additional matlab programs for this to work? and how does the combining stage work - are there any further instructions on this? many thanks! Jane

Type: make_average_surface --version Just in case yours in out-of-date, I've attached the latest make_average_surface script, which should not have the SUBJECTS bug that you describe. The file is gzipped, so do the following: - copy the file to $FREESURFER_HOME/bin - change directory to $FREESURFER_HOME/bin - type: gunzip make_average_surface.gz Then you should be able rerun the make_average_surface utility.

command line problems with tkmedit/tksurfer
by David Soscia 02 Aug '05

02 Aug '05

Guys, I am having trouble getting volumes/surfaces to show when I use the command line to try to bring them up. Prior, I was just using the csurf interface to bring up all my volumes, but now that I've make my first final surface I'm trying to get the pial surface using the command line. I type in... tksurfer </up/to/the/directory/before/mri, surf, tmp, scripts, etc> lh pial (or others, they all dont work) and i get this error every time... tksurfer: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory it does the same thing when i try to open something with tkmedit...any ideas on what the problem is?

Scripts in TkSurfer
by Sarah Rugheimer 02 Aug '05

02 Aug '05

Hello, I have a question about creating scripts for TkSurfer. I really know next to nothing about scripts in general so these are rather basic questions. There seems to be a lot of scripting commands for TkMedit but not for TkSurfer. Is there a general list of the basic commands? The commands I need to know how to do are: Open a subject Load a surface (inflated and pial) Display the color bar in a for loop Overlay a .w file Redraw the image Save as a .rgb image end loop Is this all done in a csh script? And then how do I run the script? Thank you for any help. Sarah
