[MINC-users] freeglut error on transform type in register, and default tranform type on register

[Audette, Michel]

Hi Louis, 

not sure if you got my last reply. Thanks for that. 

Both 6 and 7 seem to call procrustes(), so I suppose that procrustes() knows whether it's dealing with 6 or 7. 

Glad that I checked. 

Cheers,

Michel

Michel,

The default register transformation type is 6 parameter (3 trans, 3  
rots) rigid body.

If you need to see the actual transformation parameters, use xfm2param  
yourfile.xfm
