Comparing gene expression changes over pseudotime in different cell types

[laijen000]

Dear @ayeletAlpert ,

Conceptually, I would like to create pseudotime trajectories for each cell type, and then align/compare the trajectories for each cell type to know if a certain pathway becomes activated in cell X before cell Y from static scRNAseq data. Would cellAlign be appropriate for this kind of analysis/interpretation? I am very excited to try cellAlign since it is the only one I've found so far that discusses comparing trajectories. Thank you.
