4. Documentation#
We are currently building a documentation storage system which will host useful documents related to datasets and data owners. We will surface these documents on Guidebook.
5. Useful Syntax#
Below we will include syntax that may be helpful to other researchers in the UK LLC TRE. For longer scripts, we will include a snippet of the code plus a link to the UK LLC GitHub repository where you can find the full scripts.
