Hi Glen there is no way to get an equivalent 2D kernel to the 3D one. sorry Bruce On Thu, 30 May 2013, Glen Lee wrote: Hello Freesurfer users  I'm trying to replicate my earlier findings in 3D space by warping the data into surface  using freesurfer.  Previously, the 3D data were smoothed

there is no equivalent. I'd start with 4 and move up. doug On 05/30/2013 02:51 PM, Glen Lee wrote: > Hello Freesurfer users > > I'm trying to replicate my earlier findings in 3D space by warping the > data into surface using freesurfer. > > Previously, the 3D data were smoothed using 4mm FWHM k

[Freesurfer] How to determine a smoothing kernel size for surface that is approx. equal to 4mm in volumetric data?

2013-05-30 Thread Glen Lee
Hello Freesurfer users I'm trying to replicate my earlier findings in 3D space by warping the data into surface using freesurfer. Previously, the 3D data were smoothed using 4mm FWHM kernel and I'm wondering what size of smoothing kernel for 2D would be equivalent to 4mm for volumes. Any help w
