WebTo ease the visulization and marker gene identification, we use the MAGIC algorithm to perform imputation and data smoothing. The subsequent steps are similar to those in single-cell RNA-seq analysis, we therefore leverage the scanpy package to do this. Since we have stored the gene matrix in in-memory mode, we can directly pass it to scanpy.
