Hi - I know there is a new version of caret in the works, and I know that it is part of the connectome project, and therefore will likely have more features related to tractography. I'm looking forward to that hugely.
I was wondering what features it might have regarding segmentation. Caret is the easiest, fastest and most reliable way to segment an MRI to a good surface (certainly for macaque) that I've worked with. But the segmentation is midthickness. Will the new version segment at the GM/WM boundary and make midthickness and pial surfaces from there? When doing surface based tractography with FSL, using a WM surface that's registered to F99 is really great. But hard to make (one must do it in freesurfer, which is not designed for monkey). And, I was wondering: with good quality diffusion data, the GM/WM boundary region is often visible as an identifiable band in FA, westin and other tensor maps. In an ideal world, one would position the surface exactly on that band so that the uncertainty at the boundary can be avoided when seeding/targeting cortical regions from surface data. Perhaps there would be a way to do that? It would be of tremendous interest to me to know what plans there are in regard to this, and if, in general, the new caret will drop anything in terms of features that is relevant to segmentations, surface registration and all things macaque. And, if things are dropped whether caret5 will be maintained. best, Colin
