[Freesurfer] localGI Matlab runtime?

2013-11-12 Thread Ryan Muetzel
Hello, I was wondering if anyone has compiled the localGI code with the matlab runtime integrated with recon-all? We have a lot of data that we'd like to run through the localGI stream, however we have a limited number of matlab licenses. Are there other easy ways to parallelize this (i.e.,

Dear FreeSurfers, I have a question regarding conversion from MNI152 coordinates to MNI305 coordinates. I want to take ROIs from a VBM study and use these exact same ROIs in my vertexwise analysis. So I need to translate the x, y, z coordinates from MNI152 space into MNI305 space. In previous

Hi, I am using FS v5.3 and I had two questions regarding the calculation of cortical thickness in the stats files: 1) Is the average cortical thickness of each structure (i.e. precuneus) calculated by averaging the cortical thickness values of each location in that structure? 2) Is the mean

Thanks. What do these files look like? /export/data/brain1/RSTOM/TLR108/dmri/bvecs /export/data/brain1/RSTOM/TLR108/dmri/bvals These are the ones that the error message in trac-all.log is about, so something probably goes wrong with the conversion from your original files. Also, I recommend

The problem is that your original TLR108.bvec file is still in 3 rows, not 3 columns. You need to transpose the rows into columns. Yes, there's an example config file that comes with the 5.3 distribution and it's as usual in $FREESURFER_HOME/bin/dmrirc.example. It's also described on the

each subject is run separately through recon-all regardless of group. For group analysis, you will run mris_preproc, mris_surf2surf (to smooth), then mri_glmfit (after creating an appropriate FSGD file). Look at our group analysis tutorial and exmaple FSGD page doug On 11/12/2013 02:10 PM,
