[Freesurfer] Folding Index question

2007-11-16 Thread Graham Wideman
Folks: We're wondering about how FS's "folding index" corresponds to Van Essen's calculation (J Neurosci, 1997 Sept 15). In particular, do the FI values for each region factor out the area of the region or not. When we plot them the FI values look extremely correlated to area, but that does

Jenifer, You can use the newer fsl with freesurfer. In fact, the fsl included with freesurfer is a subset of the whole fsl package, so it can be deleted. That is, do this: cd $FREESURFER_HOME rm -Rf fsl (or mv it) ln -s /usr/local/fsl fsl and then freesurfer will use your new fsl insta

[Freesurfer] selxavg3 issue

2007-11-16 Thread Keller, Corey J.
Hi all, I'm running into some problems using the selxavg3-sess command. Previously I ran into a memory issue with matlab while running this command. However, when I run the selxavg-sess command, the analysis completes successfully. This wasn't an issue until I started averaging subjects. It

I'm considering downloading and installing fsl_v402 (centos4, 64 bit) I currently have a stable freesurfer_v401 and MNE _v252 on the same workstation. Should the destination directory of the fsl package overwrite the existing directory: /usr/local/freesurfer/fsl Or should I maintain separat

Hi Bruce, Thanks, that would be perfect! I tried increasing the number of smoothing iterations in mris_smooth, and this improves the result, but this is probably not the best way to do it. We would be very happy if you could send us a beta version of your smoothing tools. Cheers, Kim. 2007/11

Hi Kim, we do have some tools for smoothing the hippocampal surfaces, but we haven't distributed them. I could try to get you a beta version if you like. cheers, Bruce On Fri, 16 Nov 2007, Kim Mouridsen wrote: Hi Nick, The Freesurfer version I use has build stamp freesurfer-Darwin-tiger-i6

Hi Nick, The Freesurfer version I use has build stamp freesurfer-Darwin-tiger-i686-stable-pub-v4.0.1 After conversion, read_asc.m doesn't work - seemingly due to a dimension problem. In the code I see that 5 elements are expected for faces and indicies, whereas only 4 elements are provided in the
