[Freesurfer] recon-all dimensions

2015-02-05 Thread jwaugh
Hello Freesurfer, My MPRAGE dimensions are 1x1x1.33. The output of recon-all appears to be 1x1x1, judging by the fact that the aseg.stats columns for voxel number and volume in mm3 are identical. Should I conclude from this that recon-all resamples the scan into 1x1x1 voxels? Thank you, Je

Thank you Anastasia. Unfortunately, I posted the question to the FSL list first and after a few go-rounds with clarification and more info, they felt like it was potentially a problem of the calls to the bedposts command from within Freesurfer. Their final assessment was that there should be n

[Freesurfer] Variability in bedpostx output

2014-02-11 Thread jwaugh
Hello all, I have run bedpostx on a series of DTI scans over ~1 year, the earlier ones in stable 5.1 and later ones in 5.3. I'm seeing quite a lot of variability in intensity from the earlier to later versions - re-running bedpostx in 5.3 on an older scan and comparing with 5.1 yields up to 10%

Thanks Nick, I have group of subject's for which recon-all was run in versions prior to v5.2, but subsequent steps (such as mri_cor2label, func2roi-sess, etc) were run in v5.2. Does the v5.2 bug affect steps beyond recon-all? Thanks, Jeff Freesurfers, > > The new version of Freesurfe

I have checked the label file directly - it is of comparable size with others, and has the same structure. I've rerun the mri_cor2label command and regenerated the labels for all subjects. Most confusing, func2roi works for some subjects in this cohort and not others. In contrast, the whole coho

Expanding this question a bit futher... It looks like the cutting planes are used for cleaving surfaces. Is there a comparable tool for cleaving a volume into distinct sub-volumes (e.g., medial and lateral)? Thanks, Jeff > > > > - Forwarded Message - > From: Anupa AV > To: Bruce
