I have a data set (the same brain you have seen donna, but a new data set) in which the far rostral tip is missing.
I'm not expecting a positive answer, given my inter-mediate level skills in caret, but: would it be possible to create a surface from this data, and perform surface registration of F99 and associated data onto it BUT have the registration take into account the missing tissue at the rostral end? i.e., it knows that the tip of the brain being registered to is missing, but is present in the brain being registered. basically, regions are missing from my data. Could surface registration take that into account, and ignore that tissue? maybe the only way is to convert all F99 data to volumes, cut the tissue off the F99 mri, remake the F99 surface, put the volume data back on the surface? But I'm hoping for a border-based solution. i.e. cut the tip off F99 in the surface domain. It's unfortunate that the tip is missing. It is due to compaction due to the brain sitting in the fridge for maybe 6 months. There are two reasons to use this data over previous data from the brain which was taken when it was fresher. mainly we have a new DWI set with more gradients, and that data is really good despite the age of the brain. secondly, the new data has a structural scan that's perfectly registered to the DWI, which was not true before. any help appreciated.
