Hi Will,
to transform standard space ROIs into native space of individual subjects, you will first need to map some image from each subject into standard space. This can be done using e.g. spatial normalisation or segmentation. These mapping methods will compute parameter sets (deformation fields) that allow to map images from individual to standard space as well as from standard to individual space. Depending on the kind of deformation field (forward/backward) you can then use e.g. the deformations utility to map your standard space ROI onto individual subjects.
Best,
Volkmar
