compatibility question
by Jason Connolly 01 Jun '10

01 Jun '10

Dear Free Surfers, I'm having a problem I've seen posts about in the archive, but have not been able to see the solution to it. If I start tksurfer bert rh pial (as the example says), the display only shows a small fraction of the brain and nothing more. I've tried some of the suggestions such as zooming, the 'Auto redraw' option, but to no use. I have tried on two of our Linux machines, with CentOS 5, either logged in locally or remotely with NoMachines. I've got external video cards and the GLX gears works fine at ~100 FPS (remotely) and ~1000FPS (locally). The machines have 8 processors, are 64 bit, 500 GB+ hard drives and 4GB of RAM, and external NVIDIA compatible video cards. A colleague who is running Fedora 11 has no problems. Is this an OS type problem and any way to fix it? Thanks in advance for your help Best wishes, -Jason

Using peak activation voxels to determine structural areas of interest
by Nathan Dankner 01 Jun '10

01 Jun '10

Hello all. I am considering using peak activation voxels (with coordinates either in talairach or MNI space) gleaned from fmri studies in our lab to determine a priori areas of interest for examining group differences in cortical thickness. Is this something that is possible in freesurfer? In particular, I would ideally like to be able to tell freesurfer how large of an area to examine around a particular peak voxel for each subject as opposed to tracing an ROI each time. I am not particularly well versed in the technical aspects of things such as blurring kernels, but I am assuming that the amount of blurring done by freesurfer will affect the ideal circumference of any sphere around this peak voxel. Any suggestions as to how to go about this? Please let me know if any more information is necessary. Thanks, Nathan

Exporting volumes from freesurfer subject folder
by Weisinger, Brian (NIH/OD) [E] 01 Jun '10

Is there any fast way to take out a specific volume from a group of subjects so as to where I could pull out the caudate and hippocampus volumes for each person to analyze statistically between groups? Thank you, Brian Weisinger

make_average_subject with large cohorts
by Marie Schaer 01 Jun '10

01 Jun '10

Hello everybody, I have a problem running make_average_subject for a large number of subjects (>400) on a Mac Intel. I tried with different Freesurfer versions (all the log outputs are attached). Using the freesurfer version 4.3 and 4.4 the make_average_subject script always stop at the 297th subject with the error "Cannot allocate memory". I already tried to uncomment the line "limit descriptors unlimited" or to set it to various values, as proposed in the mailing list, but without success (it always stop at the 297th subject). Then I tried with the Freesurfer version 4.5 (therefore I had to recompute the lh.inflated.H and lh.inflated.K which are not automatically produced in previous versions), but with the 4.5 version I got a strange "license error" message in the middle of the script (and my licence is certainly fine as I can run any other script without problems). Does anyone have an idea? Many thanks in advance for your precious help, Marie

using custom .tif files and .gcs files
by Danny Kim 01 Jun '10

01 Jun '10

Hi all, I was wondering if there are flags you can specify to use your own .tif and .gcs files in -autorecon3 processing pipeline. Currently, I am calling up individual processes to double check the results, but in the long run it would be useful to just automate this. Thanks Danny,

scalp mesh
by Marcel Heers 30 May '10

30 May '10

Dear all, while I am doing my first steps using freesurfer, I am searching for a scalp mesh, which I could use for the brainstorm toolbox. Is there a scalp mesh produced during recon-all, which I can use for this purpose? Thanks for every hint! Marcel

?h.aparc.stats - GrayVol
by Houman Ebrahimi 30 May '10

30 May '10

Hi, Regarding information in the ?h.aparc.stats files; for a purely surface based structure such as the entorhinal cortex, why is there a discrepancy between the "GrayVol" value and the derived value of "ThickAvg" x "SurfArea"? Also the values for entorhinal "GrayVol" that we are getting are somewhat (up to 2x) larger than those presented in the recent paper published by your group (Dickerson, BC et al. Differential effects of aging and Alzheimer's disease on medial temporal lobe cortical thickness and surface area. Neurobiol Aging 2007). Is the standard (v4.5.0) segmentation map different to that used in your study? or is there some manual manipulation/segmentation that is required and not part of recon-all? Thank you dearly for all your help! Houman
