Research direction
Start by reproducing the shown sc.pl.paga call, including root='neoblast 1', and inspect the root parameter handling at that entry point. The issue does not state the expected behavior or name files or tests, so completion would require clarifying whether a string root should be supported and defining the corresponding fix and verification.
