libtk8.3.so error
by Bosky Ravindranath 21 Aug '05

21 Aug '05

I recently installed freesurfer on my Linux machine that runs RH9. When running tkmedit , I get the following error: tkmedit: error while loading shared libraries: libtk8.3.so: cannot open shared object file: No such file or directory I tried a solution posted to a simliar problem by downloading the lib files, but I got this message: rpm -i {tcl,tk}-8.3.2-1.i386.rpm package tcl-8.3.5-88 (which is newer than tcl-8.3.2-1) is already installed How do I get rid of this problem? Also, is the subcortical segmentation feature released in freesurfer-Linux-rh9-dev20050729.tar.gz? Regards, BR

mri_watershed
by Sasha Wolosin 19 Aug '05

19 Aug '05

We use an anatomical analysis program called Brain Image in our lab. We would like to speed up our analysis in Brain Image by replacing manual skull stripping with FreeSurfer's automated skull strip program. For this we would need to do a skull strip alone, without adjusting intensity values or contrast. Is this possible? Is this a reasonable thing to do? I have run mri_watershed with the input from orig on several subjects, and the output volume looks much brighter than the orig volume. Does mri_watershed normalize intensities or change the contrast in order to strip the skull?

new freesurfer atlases for dev
by Doug Greve 19 Aug '05

19 Aug '05

For those in the NMR center using the freesurfer dev environment, there will re a change in recon-all to use "new" atlaes by default. This change will be live on Monday. The new cortical atlases are based on automatically filling ventricles and subcortical structures using the automatic subcortical segmentations (asegs). This is part of the "autorecon" stream accessed with the -autorecon flags (ie, -autorecon-all, -autorecon1, etc). The new subcortical atlas is based on 40 subjects. To continue to use the old atlases, run recon-all with -old-atlas. If you use any of the "stage" flags (ie, -all, -stage1, -stage2, etc), recon-all will automatically use the old atlases to maintain consistency. Specifications of individual steps (eg, -surfreg) will use the new atlases. To help keep track of which atlases were used, recon-all now stores he names of the atlases used for a subject in the following files located in the subject's scripts directory: mri_em_register.atlas.dat - subcortical atlas (new=RB40_talairach_2005-07-20.gca, old=talairach_mixed.gca) mris_register.atlas.dat - cortical registration atlas (new=average.curvature.filled.buckner40.tif, old=average.tif) mris_ca_label.atlas.dat - cortical label atlas (new=curvature.buckner40.filled.desikan_killiany.gcs, old=atlas2002_simple.gcs) If these files do not exist, then the old atlases are implied. doug -- Douglas N.

I always have a problem to coregistrate T1 images to Talairach, Is there any way to improve the accuracy of coregistration besides tkregister2? Thanks, Antao

mgz conversion
by David Soscia 18 Aug '05

18 Aug '05

hey guys, When I go to do a conversion from dicom to mgz, im getting the error: mri_convert -ot mgz Image0001.dcm . mri_convert: error while loading shared libraries: libgsl.so.0: cannot open shared object file: No such file or directory I did an ls command for this file and found no matches in my /usr/local/lib or /usr/lib directories. I'm guessing this means I need to install the proper libraries. I'm fairly new to Linux, so I don't know how to go about doing this. Any ideas? Thanks Dave David A.
