For testing purposes, I would use "BSplineSyN" as it's much more appropriate framework for both voxel and landmark contributions.

Sounds like a good idea. I didn't know the current version doesn't take into account image orientation information. Do you want to make this change or would you like me...

Thanks. I don't think the changes should affect us to much as most usage, I would imagine, are the volume and surface area calculations which should be unaffected, the latter...

Thanks @cookpa . Now I remember making these changes. Gaetan had originally written a really nice digital [perimeter estimation filter](https://www.insight-journal.org/browse/publication/852) which, if I remember correctly, was eventually integrated into the...

A pull request would certainly be welcome. Otherwise, I'll try to get to it sometime.

If I understand correctly, you have a set of input 3-D world coordinates and want to interpolate the image volume at those points, similar to the ``SetOrGetPixel`` function in ``ImageMath``....

Yeah, that's a good idea. The original implementation uses simple thresholding for "brain extraction." I'll work on this later today or tomorrow.

Yes, I've played with that in the development of our own pipeline because I think it's a good idea. I don't think I'd include it in the sysu function itself...

Are you not using the antsMultivariateTemplateConstruction.sh / antsMultivariateTemplateConstruction2.sh scripts?

So I'm guessing that you're registering a bunch of images to the MNI template and averaging the result. If so, it's a perfectly reasonable approach but this would not be...
