Describe the goals of the changes to the analysis module.

This issue tracks adding a script to train a SingleR model from a given osteocar reference file. We'll have a few references, but the script should call one at a time from the analysis module's run bash script.

Code will be similar to this from NBAtlas prep: https://github.com/AlexsLemonade/OpenScPCA-analysis/blob/main/analyses/cell-type-neuroblastoma-04/scripts/01_train-singler-model.R

What will your pull request contain?

• script to train singler
• run script from module bash script
• environment updates where needed

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

Presumably this is when SingleR gets added to renv

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

No

If known, when do you expect to file the pull request?
