tksurfer for MacOSX second try for those courageous people
by Yasunari Tosa 16 Dec '04

16 Dec '04

The issue was that MacOSX version of tksurfer could not read annotation file due to the bug in freesurfer code. My first try worked only at the developer desktops ;-) For those who are courageous, please try "again" the following "alpha" version. At least it worked at the original poster Brian at UCSD. (Thank you, Brian, for your patience.) There are three files provided at our ftp site: surfer.nmr.mgh.harvard.edu: use anonymous with your email address as a passwd. ftp> cd transfer/outgoing/birn/tosa/Mac ftp> bin ftp> get tix8.1.tar.gz ftp> get tksurfer ftp> get tksurfer.tcl IMPORTANT: 1. The tar file tix8.1.tar.gz must be extracted at /sw/lib so that you will end up having /sw/lib/tix8.1/* files. tksurfer will look for /sw/lib/tix8.1 directory for Tix initialization. (Another way is to read http://surfer.nmr.mgh.harvard.edu/faqomatic/cache/55.html (thanks to Kevin). install tix fink unstable package.) 2. Please keep the old tksurfer.tcl (rename it) just in case and replace it with the new one. This tksurfer uses Tcl/Tk 8.4 version, not 8.3. If you don't have these, don't install.

mri_convert fix to address Analyze export
by Kevin Teich 16 Dec '04

16 Dec '04

We found a problem in writing Analyze format data. In particular, we were not writing the correct data_history orientation information, even though the .mat file was being written correctly. Since Freesurfer uses the .mat file if present, Freesurfer will not be affected by this bug. The problem is restricted to the case of using non-Freesurfer software to view or process Analyze data exported by Freesurfer. A new version of mri_convert fixes this bug. We're not releasing updates for the rest of the Freesurfer binaries that write data (and will write the incorrect Analyze volumes) in the interest of space, so if you are exporting Analyze data for use outside of Freesurfer, please use mri_convert as a final step. Thanks to Darren Weber and Graham Wideman for Analyze format information. Please see the README in the archive for more details.

skull strip

Dear experts, Thank you for answering basic question. Iam using Linux version of Freesurfer on Pen4 PC, and trying to run "Process Volume" with my anatomical data which was acquired by Siemens Allegra 3T maschine and converted to analyze format. "conversion" and "normalize intensities" were OK and COR001-COR256 were written in "orig" and "T1" directory. but next process failed and following message appeared. No COR-XXX file is written in "brain" directory. New mri-watershed" file is in bin/Linux directory as indicated by mailing list.

white matter fill
by Kai Schreiber 13 Dec '04

13 Dec '04

Hi, -what might be causing freesurfer to go through the motions of doing the white matter fill without actually writing any files? I do not find an error message anywhere, the status window shows the fill as "done", but processing stops, because there are no files created. Cheers, Kai

pial surface ill defined
by Kai Schreiber 10 Dec '04

10 Dec '04

Hi, when we fit a surface to our anatomical data, everything works fine without error messages. However, looking at the fitted surfaces in the end, the original surface / white matter boundary looks fairly good, while the pial surface is not at all related to gray matter and follows the original surface very poorly. Also, it quite frequently runs across the original surface. Are we doing anything wrong? Kai

mris_anatomical_stats
by Calabrese Massimiliano 08 Dec '04

08 Dec '04

Hi everybody, Currently, we can use mris_anatomical_stats to report statistics such as thickness +/- std. dev. over the list of brain regions, as created by the parcellate_subject program. We are wondering if it is currently possible to produce similar statistics, but not just on thickness, etc., but also on data that we can supply externally. For example, we can create a file that contains a list of nodes and corresponding data values. Is it possible to have the mris_anatomical_stats program create statistics on a region-by-region basis from our supplied data? Thanks a lot for your help Massimiliano Calabrese Imaging Group NeuroImmunology Branch NIDS, NIH and Rick Reynolds SSCC/NIMH/NIH

Stats and viewing parcellation problem
by Brian Schweinsburg, Ph.D. 07 Dec '04

07 Dec '04

Hi All, I am having problems computing stats using the parcellation file. In addition, when I try to display the parcellation results in tksurfer (File -> Label -> Import Annotation -> rh.aparc.annot), which were completed without an error message using parcellate_subject-rh, I get an error message. I am not sure how to procede. Any hints? In both error logs, there is a reference to an older location of the Simple_surface_labels2002.txt file, which never existed on my machine. Is that related to the problem? My machine is a powerbook G4, OS X 10.3.6 with freesurfer-20040218. I appreciate any assistance.

wmfill
by Margaret Duff 06 Dec '04

06 Dec '04

Hi, I keep getting an error message after I run Create Surface. It is similar to questions found in the archive but those solutions did not work and this problem did not occur for the first 2 brains I reconstructed. I get an alert that the Images (filled): /subjectsdir/mri/filled/COR-001 not found. wmfill first. I thought the first step was to fill the wm so these files should have already been created. Thanks for any help, Margaret
