Hi,
The tool in Tools>registration>Rigid with mutual information obviously only does what it says, i.e. a rigid registration. This tool box is linked to the AimsMIRegister command, for which one of the parameter when looking at the help says: --dir <filename: AffineTransformation3d>. My question are the following: does that implies that there is a way of getting affine and not rigid registration with that command? If not, is there a command to do a MI registration in BrainVisa?
Cheers,
Rv

Hi,

In fact you can't use AimsMIRegister in order to compute an affine registration. Sorry, "AffineTransformation3d" mention has been written by default in the help, but it is an error.
AimsBlockMatching command is available to compute an affine registration but set the --transfo option to 3.
If you need, you can indicate a motion to initialize the registration (usually a rigid motion) by using -m option.

Do you know this part of documentation: http://brainvisa.info/doc/aimsdata-4.3/ ... s_training
and http://brainvisa.info/doc/index_commands.html
You could find some tricks on aims commands.
