Using BedPostX and ProbTrackX, I did probabilistic tractography from several seeds to contralateral destinations, in order to obtain homotopic tracts (e.g. left IPS to right IPS).

For each subject, I would like to map each of these tracts on a standard brain, in order to end up with an image that looks something like this. I expected this would be shown in the fdt_paths.nii.gz output, but it isn't.

Ideally I'd like an image containing all these homotopic tracts (3 of them) on the same brain, however obtaining one tract at a time (each superimposed on the standard brain) would be fine as well.

Thanks in advance for any help!
