freesurfer + fsl
by Don Hagler 14 Nov '05

14 Nov '05

I had a similar problem running Linux RedHat E4. It seems that fsl and freesurfer have incompatible versions of tcltktix. One solution is to always run freesurfer and fsl from different terminal windows.

Unfortunately, fsl doesn't work after the installation of Freesurfer. This is the error message I get when I try to open the fsl GUI: Error in startup script: no suitable image found. Did find: /Applications/freesurfer/lib/tcltktixblt/lib/ libtix8.1.8.4.a: unknown fi le type, first eight bytes: 0x21 0x3C 0x61 0x72 0x63 0x68 0x3E 0x0A while executing "load /Applications/freesurfer/lib/tcltktixblt/lib/libtix8.1.8.4.a Tix" ("package ifneeded" script) invoked from within "package require Tix" invoked from within "if { [ string first tclsh [ file tail [ info nameofexecutable ] ] ] ! = 0 } { package require Tix tix configure -scheme TixGray option add ..."

Any help to get FSL working again is highly appreciated!! Peter

I looked through the recon-all.log file, but I could not find any references to mris_ca_label or mris_anatomical_stats, do you know what else I can search for? I found this warning in several places, but I don't know if it is related: INFO: Volume /tmp/mritotal_12360/orig_8_dxyz.mnc cannot be found. In the recon-all.status file there is another warning: Euler: NHoles = WARNING: Number of holes is not zero This subject was previously manually edited with an older version (oct 2003 release). I made four copies of the subject and ran each of the following in both the 2003 release and the latest stable release: recon-all -subjid subject -stage3 -stage4a -stage4b recon-all -subjid subject -all I only saw the warnings in subjects run with the stable release, (in the 2003 release NHoles =0). Could I be missing some files? Thanks, Sasha >>> Xiao Han <xhan(a)nmr.mgh.harvard.edu> >>> If you run "recon-all -all ...", then mris_ca_label and mris_anatomical_stats should be included as the final two steps. You can check the recon-all.log file under each subject's script directory to see why mris_ca_label wasn't executed in your previous run of recon-all. -Xiao On Mon, 14 Nov 2005, Sasha Wolosin wrote: > That might have been what happened.

long time to finish a case by recon-all
by tulu 12 Nov '05

12 Nov '05

Dear Freesurfer experts, First of all, I thanks for your wonderful tool. I run the recon-all -autorecon-all script and it can finish my mri data without error. The only problem is it need 3 days (about 72 hours) to finished one mri data. I wonder if anyone have same experience and how to correct it (I use P4 2.8G CPU with 2G RAM, OS is Linux Fedora Core 4). Thanks replay KL chen

mri_surf2surf
by Irina Sigalovsky 12 Nov '05

12 Nov '05

Hello, I have a *.w file which I map onto a different subject (say, average7) using mri_surf2surf. Let's say that my original file has N vetrices equal to 100 and all other equal to 0. Is there a reason why a "new" *.w file (output of mri_surf2surf) has: - N1 vertices equal to 100 where N1 is not equal to N (not even close); - some vertices that have values that are neither 100 nor 0 (i.e., some new values are introduced). This is how I use mri_surf2surf: mri_surf2surf --hemi lh --srcsubject iss09newnew --srcsurfval iss09newnew/surf/R1map0.8LP2Thresh15-lh.w --src_type w --trgsubject average7 --trgsurfval average7/surf/iss09_R1mapThresh15-lh.w --mapmethod nnfr --trg_type w My second (unrealted) question is where I can find information about MNI Talairach coordinates for a given surface (i.e., what file contains this information). Thank you, Irina

RE: [Freesurfer] problems with spheres

Florent, I'm using MapIcosahedron from the SUMA package to do the spherical averaging and the distortions are visually quite striking in an area that is fairly important in this study. Here's a screen shot of the smoothwm surface after recreating it with an icosahedron mesh: http://fmrif.nimh.nih.gov/~adamt/ridges.jpg Note the ridges along the gyrus. There is also a spike coming out of the sulcus nearby that is a little hard to see. Ziad (the developer for SUMA) also thought some sort of regional smoothing might be the best solution. If that's the consensus, we'll pursue that option. -Adam --- Adam Thomas adamt(a)nih.gov Functional MRI Facility, NIMH/NIH/DHHS 10 Center Dr, Room B1D708A Bethesda MD. 20892-1148 Phone:301-402-6351 Fax: 301-402-1370 -----Original Message----- From: florent segonne [mailto:fsegonne@csail.mit.edu] Sent: Thursday, November 10, 2005 4:51 PM To: Thomas, Adam (NIH/NIMH) Cc: freesurfer(a)nmr.mgh.harvard.edu; fischl(a)nmr.mgh.harvard.edu Subject: Re: [Freesurfer] problems with spheres Dear Thomas, Looking at the file rh.sphere.asc, it seems that the problem comes from the spherical registration that generates a spherical surface with, as you said, small triangles slightly overlapping. However, these distortions should be extremely small. If you really need to get rid of them, one hacky solution would be to detect these (small) regions and to smooth them untill the overlapping edges(faces) disappear. Since these regions are small, this should not generate large metric distortions. But maybe Bruce has some other ideas.

freesurfer on debian
by Darren Weber 10 Nov '05

10 Nov '05

If freesurfer is adopting some kind of open-source license (hoorrah!), can we do away with the requirement for a license file? Are there any components/dependencies of freesurfer that are not open-source? Does anyone have detailed instructions for a) compiling freesurfer? b) installation of freesurfer on debian? Is anyone working on creating a debian package for freesurfer? For that matter, has anyone created any rpm packages for freesurfer? Debian already has a package for minc tools, see http://packages.debian.org/stable/science/minc-tools but this does not include all the MNI tools (eg, n3 and mritotal). Comments, suggestions all welcome. Thanks, Darren

problems with spheres
by Thomas, Adam (NIH/NIMH) 10 Nov '05

10 Nov '05

I recently noticed that some of my subject's spherical surfaces appears to have several small, pyramid-like points on them. One example is shown here in tksurfer: http://fmrif.nimh.nih.gov/~adamt/sphere.jpg Looking at these points in more detail in suma shows that several triangles are folder on top of each other so that all the vertices are on the spheres surface, but some triangles are entirely overlapped by others. The spherical surface is here: http://fmrif.nimh.nih.gov/~adamt/rh.sphere.asc (11MB) And this is a close up of near node 141619 in suma: http://fmrif.nimh.nih.gov/~adamt/sphere_suma_zoom.jpg These distortions are causing us problems with subject averaging. Is there something we can do to fix or avoid them?

how do you include parietal lobe in the cut?
by Joongnam Yang 10 Nov '05

10 Nov '05

Hi, I know how to cut the occipital lobe and flatten it. You cut calcarine and pick three points and another point to select the plane and do "cut plane". Would someone let me know how to extend the cut so that the cut can include part of the parietal lobe? The menu bar has "whole brain cut" and "occipital cut" only. Thanks. Nam.

Hi Bruce, yep, the cerebellum was attatched, so I guess that must have been the problem.
