[Insight-users] deformable registration 3D

[Luis Ibanez]

Hi Christoph,

Did you changed the Dimension from 2 to 3
in the .cxx file and recompiled  ?

The error message is sayikng that the
image filename was not found.

You are writing a relative path in the
specification of the input Moving and
Fixed image files.

Could you please try with an absolute
path ?

Please let us know if that works or not.


   Thanks


     Luis
