[Freesurfer] hardware recommendations?

Dear list members! I wonder if anybody could recommend me hardware for a dedicated freesurfer PC. Any suggestion? Also, should I stick to Redhat 9 or is it worth to go for the new SUSE/Redhat distributions? Many thanks for your help and best wishes, Lukas _

[Freesurfer] cortical thickness stats.

Dear list members! I would like to analye cortical thickness data and wonder which is the best way to proceed... So far I have processed the data using recon all (including manual top fixing). This includes the registration using the average7 subj. on the sphere. 1) Is it a valid approach

Re: [Freesurfer] problems with mris_glm

Hi Bruce, many thanks! Actually, I wanted to try the examples first,  play around with it and than start to do the actual analysis. By the way I discovered today that I use a rather old freesufer version (20030724) and I have to admit that I did not update to the latest version. So far I have

[Freesurfer] problems with mris_glm

Hi freesurfer folks, I try to run some example cortical thickness calculations as outlined in mris_glm --help. The first step (read thickness maps, smoothing and resampling to average7 as well as saving the regression coefficient works fine, however it crashes with the complain that it does

Hi Bruce, Is there a way to define regions on the inflated brains and map those back on the uninflated brain? Best wishes, Lukas Datum: Thu, 1 Jul 2004 09:45:58 -0400 (EDT) Von:Bruce Fischl <[EMAIL PROTECTED]> An: [EMAIL PROTECTED] Kopie an:

[Freesurfer] inflation<-> area

Dear list members, I wonder if during the inflation process "areas" are preserved. Or does inflation induces local deformations? Best wishes, Lukas Lukas Scheef, MD, MSc MR-Tomography Department of Radiology University of Bonn Sigmund-Freud-Straße 25 D-53105 Bonn Fax: +49-228-287-5598 Pho

Re: segmentation

Hi Kevin, I agree with Bruce. It sounds like a BIAS field problem. You might want to use FAST from the FSL-package to solve the problem (http://www.fmrib.ox.ac.uk/fsl/fast/) or the matlab script from http://www.psych.stanford.edu/~kalina/SPM99/Tools/vol_homocor.html Good luck! Lukas Date sent
