Hi,
I'm afraid this didn't quite make it to the release, despite what we'd hoped.
The shape analysis method was changed, but extracting the boundary coordinates with the correct correspondences didn't get finished.
If you can get the distances along the normal (or even the shortest distances to the boundary of the manual segmentation) from an average shape boundary (the set of voxels along the edge) then it is easy to run the resultant data through randomise as is done with the current first_utils output. The difficulty is defining your average shape and then getting the (signed) distances. It is possible to do via scripts with existing FSL tools if you want it right now, otherwise we hope to offer an easier option within the next 6 months.
All the best,
Mark

You also told that a tool for this was in preparation en would become available in weeks, but if not, I should mail you. So, I would not seem to be impatient but I'm very interested in this tool/how to import segmentations in FSL. I hope you can help me.
