Combining ANTs/itk and FSL style deformation fields

[Julia Huntenburg]

Hi,

does anyone know of a way to apply deformation fields derived from FSL (warpfield from convertwarp or alternatively shiftmap from fugue) and those derived from antsRegsitration in a single transformation?

For affine transforms there is the c3d affine tool to get FSL style matrices into itk format which can be used in antsApplyTransforms. Does something similar exist for deformation fields?

Or alternatively, is it possible to get the ANTs deformation field into a format that FSL can handle?

Many thanks in advance!
