Brain skull size
by Akemi Tomoda 15 Apr '04

15 Apr '04

Dear list, Is there a way to get brain skull size of subjects using FreeSurfer? I already have got Brain Size (cm3) from the output of mri_strip_skull, but my guess is that it would be different from the skull size. I'd be most grateful if anyone could let me know of the way of outputting these values.

Fix for mri_watershed
by Kevin Teich 14 Apr '04

14 Apr '04

There's a new version of mri_watershed available. The fix is to eliminate s problem with the WM value. The previous version sometimes used the pon area for the WM value.

mris_flatten usage
by Jonathan Polimeni 03 Apr '04

03 Apr '04

hello all! i have a fast question regarding the usage of mris_flatten: what are the available command line options? the usage message displayed by mris_flatten only lists the "-w" and "-distances" options, but i also know of the "-p" option, and there was an earlier posting that mentioned a "-s" option as well. does the option "-p <N>" repeat the flattening procedure N times by feeding the output of flattening k into the input of flattening k+1? does the "-s 1" option turn the scaling off? is this a binary flag? is the default then equivalent to passing "-s 0"? thanks in advance! -jon

error
by Mary Fitzsimons 02 Apr '04

02 Apr '04

Need help! In csurf when I click on volume or surface to display images the following error message arises the same thing happens if I try to use tkmedit/tksurfer from the command prompt. Error while loading share libraries: libtk8.3.so:cannot open shared object file: no such directory I cannot locate libtk8.3.so on my computer so I looked up RPMfind on the net a download is available but it leads to a broken link can anyone send me this library? >From the websearch I found that libtk8.3.so is part of a graphical toolkit TCL scripting language. Do I need to have TCL on my machine? Are there any other specific requirements to run Freesurfer? Many thanks Mary Fitzsimons

Looking for correct coordinates
by Daniel Goldenholz 31 Mar '04

31 Mar '04

Hi freesurfer folks. I have a pair of inflated brains that I'd like to work with in matlab. I found a nice function called "read_surf.m" which works very well. But I noticed that the two hemispheres cannot be viewed at the same time, because their locations overlap! I pushed one to the left and one to the right by an arbitrary amount, and this looked a bit better. But I was hoping to put the position of the inflated brain in the correct spot so that I could correlate MEG info with these surface files. What else do I need to know about positioning these brain surfaces? Thanks -- Daniel Goldenholz -----------------------------------------------------

remote desktop turns blue?
by Nguyen, Thang Q 31 Mar '04

31 Mar '04

Hello all, I don't know if anyone has had this problem before but when I remote desktop into a PC running freesurfer (csurf), the brain image in tkmedit turns blue. In addition, tksurfer doesn't load. When I relog on to the PC, I can reload tkmedit and it works fine. Here are some specifications: Running freesurfer-20030724 Remote desktop with windows XP Pro to another windows XP Pro PC Running Reflections X on the PC desktop Running RedHat v9.0 on the compute nodes In addition to all this trouble, after editing in tkmedit and creating a new surface, the surface doesn't reflect the new changes. This hasn't happened before. Does anybody have any ideas on what contributes to these problems?

Pial Surface
by Keyma Prince 30 Mar '04

30 Mar '04

When you look at the values that are produced by mris_anatomical_stats for surface area, are these values the same as pial surface area? Is the pial surface the same as the inflated surface? -Keyma

Snapshot of version
by Jonathan Wisco 25 Mar '04

25 Mar '04

Hi, I was wondering if I someone could send me a snapshot or pointer to the freesurfer recon tools for cortical inflation that was being used between Sept 2003 and Mar 2004. I suspect that the version changed somewhere in the middle of this time period and would like to analyze my data using the same version of freesurfer. Thanks, Jon --- Jonathan J.
