combineSamps won't read global occupancy

[drnickisaac]

One of the first lines in combineSamps is:
REGION_IN_Q <- paste0("psi.fs.r_", region)

This means that combineSamps can only read information from the regions defined in sparta. It cannot read the global occupancy, which is simply psi.fs. This is a problem.

I don't understand how it is capable of reading the UK occupancy. I didn't think we defined UK as a region aggregate.
