How to compare essential genes in several cell lines of certain lineage at once?

Q&A

I need to look through a certain cell line lineage for all top essential genes, for future CRISPR for potential slicing and silencing. For instance, I need all head and neck cell lines, and I’m looking for essential genes that overlap amongst them. I understand it is possible to manualy go through all 95 cell lines in that lineage, but is there any way DepMap has a built in utility for that?
Thank you.
