Re: [Freesurfer] Regarding Segmentation of Hippocampal Subfield

2011-09-06 Thread Koen Van Leemput
Hi Mohan, I'm afraid the smaller structures you mentioned aren't generated by our automated segmentation tools. As for the Left-Hippocampus and Right-Hippocampus labels, these are parts of the tail of the hippocampus where the people doing the manual segmentations the automated method was trained

[Freesurfer] calculating GM and WM surface-based volumes

2011-09-06 Thread Alexopoulos, Dimitrios
I have generated surfaces using the the centos4 build (version 5.0) and want to confirm that my surface-based GM and WM volumes are correct. For the surface-based GM calculation I originally used 'mris_anatomical_stats -l lh.cortex.label subjectID hemi' (run from within the 'label' subdirectory)

Re: [Freesurfer] FS-FAST modeling question

Hi, I have an update to this query. I tried using mkanalysis-sess instead of the .new version, and now I do seem to be able to get rid of intensity normalization and prewhitening (or at least, adding these flags now has an effect on betas/t-stats, and in the expected directions). The code I'm

Thank you very much for your response! May I also ask how about running CUDA and non-CUDA analyses for the same dataset? I am asking because I don't have CUDA support on one of my machines as well (It has ATI videocard). I have found a thread on that topic

I wouldn't do that either. We have actively worked to minimize the difference between CUDA and non-CUDA versions, but it's not possible to make them identical due to differences in architecture sorry again Bruce On Tue, 6 Sep 2011, Alexander Lebedev wrote: Thank you very much for your

1. Yes, mri_vol2surf will do this if you have registered the surfaces to the data (using bbregister for example). 2. Yes, this sounds correct although it's hard to say without all the details cheers Bruce On Mon, 5 Sep 2011, ZhiLiangLong wrote: Hi FS experts: I have two questions
