Algorithm 2.

Volumetric lossless registration

V1: Compute 3-D translations between L7 volumes to minimize distance between landmarks
V2: Compute 3-D elastic warps using drop-3d between V1 volumes
V3: Using lossless encoding algorithms, apply transformations computed in steps V1 and V2 to L8 volumes to generate aligned artifact mask volumes
V4: Using lossless encoding algorithms, apply transformations computed in steps V1 and V2 to L9 volumes to output registered cellular gene expression data
