I had a question and a suggestion for the code, but mostly looks good. Have you tested this locally or on staging to see if it works?

Thanks @dpca for reviewing, let me try getting local working on uploading data to fullstory before we merge this.

@dpca I tested locally and it works as expected with these additional commits. I also added Add fs-block to genome name, fragment name, sequence per Product's request to prevent possible leak of proprietary information.

Looks good!
