I could not find it this morning - I sent him an email to see where his project ended up and will get back to you.

I am not sure if anyone has looked at this in a systematic way - I know Andrew Malone (malonelab.com) had some interesting data suggest T cell doublets in transplant biopsies might be doing this. You will probably need to know the HLA typing for the sample (not great typing in single-cell data)

Awesome! Please thank Ksenia for all her help!!

totally second R for Data Science!

The 3 things that helped me the most was: 1) working in markdown to add context to my code (as well as annotated code), 2) working towards writing functions over scripts, and 3) getting comfortable with git.

Also I also found it easier to learn things when it was relevant to a research project.
