I think this one is for the caret list really. I wonder, is there a way using wb_command to generate a ribbon volume suitable for myelin mapping, from a pair of surfaces?
Unfortunately, caret "make segmentation from surface" seems to lack the required precision. It seems I've been operating with that issue for a long time without fully realising it. fressurfer mris_fill works very well. Unfortunately, the nature of the data is such that generating conformed output and reslicing is not possible without downsampling all the volumes to be mapped. And that basically won't do it turns out. one can generate surface fills that are the exact minimum voxel dimensions of the ribbon with mris_fill though. and they look great. Perfect. But I simply just cannot figure out how to resize that output and give it the appropriate header so that it's the same size, shape, alignment as the data volume to be mapped with caret and/or workbench myelin mapping. It strikes me that the 700um HCP structural pipeline or related primate pipelines that deal with non-1mm data might in some way have addressed this matter. It seems like the ribbon voxels are key here. I've traced my problems to having an accurate ribbon. I can get one, but I can't figure out how to size and align it when I can't use mris_fill -c best, Colin Reveley
