"x" vs. non-"x" tools and fast registration
Hi Dominique:

Q1 - for "reformatx" you have no choice. The plain "reformat" tool has been retired a few releases back. For the other two, the plain versions are currently more predictable and interface-stable, so I would suggest using "registration" and "warp".

Q2 - to make things fast, it is best to simply disable the optimization. For "registration" you should be able to simply set the number of DOFs to zero by adding "--dofs 0" to the command line. For "warp" I would suggest using the "--f-threshold" parameter. Specifically, using "--f-threshold 1" should virtually disable optimization. If it does not, try larger values, and just in case my memory is totally off here, try zero also.

Sorry for delay and vagueness - I am on vacation and thus slightly handicapped.


PS: as usual I will post this reply to the CMTK users forum on NITRC also; feel free to use the forum for future inquiries ;)
