There are some updates on this. I have been able to run the keypoint similarity alignment metric on a single stack in all its orientations (north, south, west and east, therefore 4 different estimations) of one of the recent SmartSPIM datasets in 3D as well as a metric approximation computed with the MIPs if we want to get a quick estimation of the transformations (sacrificing the Z translation, of course). Here are some screenshots of the MIPs:

So far, I'm getting the mean and median of the results per pair of stacks. It is important to mention that I haven't had time to migrate our metric to dask but it is in the plans so it could be used in diSPIM as well as ExASPIM. @sharmishtaa @dyf
