[Freesurfer] FS group feat

Hi, I have a 3 level feat analysis with 2 runs in each subject on the first level. At the second level these two get combined with a fixed effect analysis to produce a mean for each subject. At the third level, the second level results are combined with FLAME to produce group maps. I was able

Re: [Freesurfer] FS group feat

Once you have combined different subjects into one analysis in standard space, it does not make much sense to render it on the surface as a surface in standard space does not make much sense. You're better off sampling your 2nd level analyses onto the surface then using mri_glmfit or

[Freesurfer] Gradient Non-Linearity Distortion Correction for Allegra 3T

Dear Freesurfers, I have downloaded grad_unwarp_bash.tar.gz from the NBIRN site and am trying to follow the instructions on http://www.nbirn.net/tools/gradient_non_linearity/index.shtm and https://surfer.nmr.mgh.harvard.edu/fswiki/GradientUnwarping?action=highlightvalue=Gradient to create the

When I run dypyinfo, it lists both GLX and SGI-GLX. Does this mean that I still need to install a X11 video driver? Or is it a different problem? Thanks again, sarah From: Doug Greve [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 28, 2007 3:26 PM To: Sarah Andersen Cc: 'Paul

[Freesurfer] Another talairach question . . .

Dear FreeSurfers, In the course of checking my skull-strips I discovered that one of my subjects does not have a T1.mgz because they did not pass the automatic Talairach failure detection. I checked the transformation with tkregister2 and -fstal, and it actually looks quite good; the brain is

RE: [Freesurfer] problem viewing in tksurfer

Well, I don't know if there is a different video driver for you to try. Frankly, I just think the video of a virtual machine is just not going to cut it. For proper graphics, you really need a full, real Linux machine. On Thu, 29 Nov 2007, Sarah Andersen wrote: When I run dypyinfo, it lists

RE: [Freesurfer] problem viewing in tksurfer

Sarah, When I have seen this 'sliver' problem in the tksurfer in the past, upgrading the NVidia Linux driver fixed the problem. But that was on a native Linux system (with NVidia graphics), so I don't know what to suggest here, since a virtual Linux machine is a very different beast. I suppose
