MRIWarp

MRIWarp is a warping tool for intersubject registration of brain images constructed by Ulrik Kjems. Now he is unfortunately lost to industry but will presumably still answer emails in connection with his toolbox.

The package consists of C-functions that should compile on most (UNIX?) systems. There are also a few utility functions in Matlab, that will help to visualize the warp.

Apart from warping there are also (command line) functions for ANALYZE header information, mirroring, translation, subsampling, ...

The package cannot only be used as a preprocessing step in function neuroimaging but also as a step in deformation-based morphometry, see a reference below.
