Directions for reviewers. Tell potential reviewers what kind of feedback you are soliciting.

Which areas should receive a particularly close look?

Please check to make sure I did not miss anything

Is there anything that you want to discuss further?

For #1431 , did you want the file names listed in this column as well? UPDATE - I see these in another column, and updated a few files here. For the markdown table updates, I had used a web tool for updates, so some of the spacing came back as if there are more changes than previously, but this was the quickest way to do it I have found.

Is the analysis in a mature enough form that the resulting figure(s) and/or table(s) are ready for review?

yes

@sjspielman I think this is ready for re-review. I applied your changes and updated the BED file origins - if it was a reference file we received, linked to cavatica and if we generated, added the workflow link.
