I am not sure what you mean by "integrate options", but if you mean collecting a set of options so you don't have to specify them all every time, then yes there is. Have a look at http://www.fmrib.ox.ac.uk/fsl/fnirt/index.html#fnirt_config_files For masking out lesions have a look at http://www.fmrib.ox.ac.uk/fsl/fnirt/index.html#fnirt_inmask Good luck Jesper
