Hi Michael, while fslmaths has an option to do 2D smoothing, this is still only smoothing in a slice of the volume and has the same problems as 3D smoothing (ie, smoothing across tissue types and sulci). The 2D that FS implements with mris_volsmooth is along the cortical surface, which is

Thanks for you input Michael. For some reason, I only saw your answer after Dougla's response. Assuming that I do not want to do volume-based analysis and just want nice pics of my blobs over a 3D brain, would Michael's suggestion work? If so, what is the next step after using fslroi, as the

Estephan, I can ask our IT people about an RSS feed. Another option is to turn-on digest mode under the mailing list options. Freesurfer emails would arrive in once-a-day bundles. https://mail.nmr.mgh.harvard.edu/mailman/options/freesurfer Nick On Thu, 2009-09-24 at 12:35 -0400, Estephan

The example_func does not actually get smoothed, so smoothing itself will not affect the registration. 3D smoothing will smooth values from WM and CSF into gray and from across sulci into functionally distinct regions. For this reason we recommend not using 3D smoothing (or doing 2D smoothing

Hello all, I took the FS course last June at the OHBM in San Francisco, and am now playing with it to get to know it better. One of the slides on the talk about FSL-FS integration mentioned that the input data (from FEAT) for the reg-feat2anat command should have not been smoothed prior to
