Freeglut problem
by Calabrese Massimiliano 30 Mar '05

30 Mar '05

Hi all I've installed Freesurfer and when I open csurf to edit segmentation on images, I get the following error: /usr/local/freesurfer/bin/Linux/tkmedit: error while loading shared libraries: libglut.so.3: cannot open shared object file: No such file or directory Now, I've installed Freeglut and still get the above error. I can see the libglut.so.3 library in /usr/local/lib and this is in my $PATH. Any ideas why the error exists? Thanks a lot for your help Massimiliano Calabrese Neuroimmunology Branch, NINDS, NIH and Willy Calderon NINDS, NIH.

tkmedit problems
by Mike Angstadt 29 Mar '05

29 Mar '05

Hi, I just installed freesurfer and was trying to run tkmedit. At first it couldn't find the correct shared libraries because we have 8.4 of TCL and TK installed, so I made symbollic links to those to satisfy the dependency, and it at least gets through that check. However, now when I try to run it remotely or on the local computer I get first the following: Xlib: connection to ":0.0" refused by server Xlib: No protocol specified even so a window pops up for several seconds then disappears. The .xdebug_tkmedit file says: Tix_Init returned 1: version conflict for package "Tcl": have 8.4, need 8.3 ERROR: Initializing Tix Error initializing Tix So obviously it's still having a problem with the newer versions of Tcl. Does anyone have an idea of how to fix this without uninstalling the newer Tcl/Tk? Incidentially tksurfer works fine. Thanks -Mike

flattening
by Ronald E Bryan (rbryan＠Princeton.EDU) 26 Mar '05

26 Mar '05

Hi We are trying to create flattened surfaces for doing surface based statistical analysis of ventral temporal cortex, but the flattening method described in the freesurfer manual creates cuts right through this region. It would be better for us if we had a contiguous region of VT cortex to analyse. Are there any other slicing methods known that produce good flat maps without going through VT? thanks, -Ronnie

Re: [Freesurfer] new tcl and tk

Hi, I saw that this question has been asked a few time with no response so I've started working on a workaround. So far, I've tried creating symoblic links from libtkx8.3.so to libtk8.3.so and the same with libtclx8.3.so. When I do this and try to view a volume it opens and the title bar is set but then crashes, before an image actually comes up, with the following error: /opt/freesurfer_alpha/bin/Linux/tkmedit bert T1 -csurf /opt/freesurfer_alpha/bin/Linux/tkmedit: symbol lookup error: /opt/freesurfer_alpha/bin/Linux/tkmedit: undefined symbol: Tcl_CreateInterp Does anyone know what this error means or a way to fix it? I'll keep working on this and post anything that works, but any help would be greatly appreciated. Thanks so much. -Xander ---- Original message ---- >Date: Tue, 22 Mar 2005 14:36:02 -0600 >From: Xander Meadow <xmeadow(a)uchicago.edu> >Subject: [Freesurfer] new tcl and tk >To: free surfer <freesurfer(a)nmr.mgh.harvard.edu> > >Hi, > >I'm running Freesurfer on RedHat Enterprise linux stations and we >recently updated to version 4 of RedHat.

Talaraich problem
by Calabrese Massimiliano 22 Mar '05

22 Mar '05

Hi all I have a problem ( computer crash) during talairach program in recon-all -stage1 , does this mean that There is a problem with MINC installation or the MINC program? Is this the software to compute the Talairach transform? I had to do again the installation of freesurfer and it is possible that my MINC installation is not correct. The problem seems to be in mritotal -verbose -debug -clobber -protocol icmb orig/orig.mnc transforms/talairach.xfm at this point the linux freeze If I run stage1 without talairach there are no problems. Thanks a lot for any advice Massimiliano Calabrese NIB, NINDS, NIH.

correcting bad euler numbers
by Goldman, Aaron (NIH/NIMH) 22 Mar '05

22 Mar '05

Hi. After doing stage 1-4 with all the manual edits, I have a fair number of surfaces that came out with an euler number of 1 instead of 2. However, looking at the inflated surfaces, I don't see any obvious defects. In situations like this, what would be the most efficient way to locate the problem area and fix it? Thanks, -Aaron- Aaron L. Goldman Post-Bacc IRTA Genes, Cognition and Psychosis Program, NIMH Building 10, Room 3C108 Phone: (301) 435-0944 Email: <mailto:aarong@mail.nih.gov> aarong(a)mail.nih.gov

new tcl and tk
by Xander Meadow 22 Mar '05

22 Mar '05

Hi, I'm running Freesurfer on RedHat Enterprise linux stations and we recently updated to version 4 of RedHat. Doing that updated our libtcl and libtk libraries to libtcl8.4.so and libtk8.4.so. Our problem arises because freesurfer is still looking for version 8.3 of both libraries. Is there a settings file where I can make this change? Or, am I behind in my version of freesurfer? I thought I'd stayed up to date, but I could easily be mistaken. Thanks so much. -Xander

FW: [Freesurfer] thickness measures

-----Original Message----- From: freesurfer-bounces(a)nmr.mgh.harvard.edu [mailto:freesurfer-bounces@nmr.mgh.harvard.edu] On Behalf Of Kirk, Gregory Sent: Tuesday, March 15, 2005 1:49 PM To: freesurfer(a)nmr.mgh.harvard.edu Subject: RE: [Freesurfer] thickness measures Hi I would like to know if anyone has much experience doing pediatrics with freesurfer. I was able to get what look like good results from a 2 year old and a 16 year old, the surfaces look good with only automated topology fixing. An 8 year old needs a lot of manual work. The +- on the cortical thickness was .8 and .9, I don't know if that is larger than usual or not, for averge of a hemisphere.
