[Freesurfer] mri_robust_template- Segmentation Fault

2012-06-28 Thread Usman Khan
Hi there Freesurfer, I am running into a seg fault while running mri_robust_template on freesurfer-Linux-centos4_x86_64-stable-pub-v5.1.0 on a Centos6.2 build. Thinking that this may perhaps be an OS-related issue, I tried to download FS binaries from http://www.freesurfer.net/pub/dist/freesurfer/

[Freesurfer] Combining linear transformations

2012-07-10 Thread Usman Khan
Hi FreeSurfer, I have two images. One MPRAGE (1x1x1mm) and a T1-weighted (0.682x0.682x3mm) image used for CBV mapping. We have run FS, with hippocampal subfields on the MPRAGE and would now like to transform the posterior probability maps to the T1-weighted CBV space. I have been using 1) mri_vol2

Hi Lijie (cc to mailing list), I wrote a script to do just this in July. Here is a link to a tar file. It requires knowledge of matlab and bash, but is pretty straight forward. It https://www.dropbox.com/s/s1f78j2ozv1gw8q/subfield_to_ROI.tar.gz a) transforms the subfield probabilities to nu.mgz
