Cycle Alignment
Microfluidics, thermal expansion and other temporal effects may perturb the tissue between imaging cycles. To ensure positional consistency for reliable marker expression, tissue displacement is corrected using 3D phase correlation developed by Dr. Stephan Preibisch, Ph.D. at Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG). For each cycle, the nuclear stain pattern is compared to that of the reference cycle, which by default is DAPI of the second cycle. The calculated offsets are used to align all cycles using rigid translation.
