AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

On the differences between Matlab and AFNI, I think one difference is the medfilt3 function in Matlab uses a rectangular neighborhood while the 3dmerge winsor filter and 3dMedianFilter use spherical neighborhoods. Besides these, also consider 3dLocalstat. Although it's relatively slow, especially with large neighborhoods, it has flexibility for 2D,3D, sphere and rectangular block neighborhoods, so you could potentially do a median filter within-plane only if you like.
