Applying transformations to coordinates?
Hi there,
I have some segmented data, where we have defined the centroid position of many cells. Using the anatomy of this brain we have registered it to a template, and so the registration parameters are calculated. I am wondering if there is a way to apply the reformatx-type transformations to x/y/z centroid coordinates.
I was thinking of making an image volume out of the coordinates, where each centroid position defined by an intensity value, but if there are any significant deformations, I guess this would cause the voxel to be interpolated and its intensity to change.
We could also do the segmentation after reformatting, but I guess the original non-warped data will always be better.
Thanks for your help!
