Hi - I have a large number of .dscalar.nii files. They are surface maps. They cover every surface node, except for the medial wall.
I'm turning these into vectors and working with them in matlab. and that's great. however: I also want to analyse the relationship of these data to data that's already on the surface as func.gii (e.g. curvature) and now I have a problem since the cifti data isn't the same size as the surface. I just need the curvature (or other surface metric) to be a vector with the same length as the cifti and where the indices of the vectors represent the same nodes in both. I don't need a working cifti or gifti file, just the data as vectors of numbers in matlab. I suspect using the node indexing info in the cifti header as a guide for what metric nodes to delete (or add) is one way to go. but maybe there is a simpler way I've missed? maybe make a dscalar.nii mask of just the missing nodes and then -cifti-merge-dense that with the data (expand the cifti rather than contract gifti)? best, Colin Reveley _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
