Hi everyone,
I wonder if anyone knows how to create masks for optional targets in FSL DTI prob track?
I am thinking it involves using a brain atlas in FSL view, but I am unsure if I will have to manually draw slices using the lightbox view, or if I can automatically turn a selected atlas region into mask?
If you can automatically turn a selected atlas region into a mask, does anyone know about the steps required to do this? I have a standard image: FMRIB58_FA_1mm loaded with the Juelich Histological Atlas on, and I have opened the MNI structural atlas and selected the frontal lobes. I have 5 seed masks that correspond to regions of the corpus callosum, and I would like to get the probabilities associated with fibres from each submask reaching some targets regions ie frontal lobes etc.
If you have to manually draw over selected regions it could be very difficult to create masks as I think this would involve drawing surfaces rather than planes. it almost seems unachievable to get a reasonable level of accuracy by eye.
Thanks.
From Russell.
