Part of #1143

Describe the goals of the changes to the analysis module.

Following #1146, we will be ready to create normal references for SCPCP000004 to references/normal-references. This issue tracks adding a script to create the normal reference(s) identified in X.

Simultaneously, we'll need to add a project-specific workflow script to run SCPCP000004 samples through the module pipeline similar to what we have for SCPCP000015. We'll want to get the script that creates references running in this workflow script, which should also be added to run-analysis.sh.

By adding these scripts at the same time, we'll be able to have it tested in CI right away.

What will your pull request contain?

Two new scripts, one updated GHA, and associated documentation:

• An R script in scripts to create and export normal references
• A bash script in project-workflows to run this project, for now just with this step to create references
• Updates to the module GHA to download the NB data needed for this code

Will you require additional software beyond what is already in the analysis module?

No

Will you require different computational resources beyond what the analysis module already uses?

No
