Problems retrieving items from a list using a reference rather than an integer - can you help?

Excellent!

I'd also like to see a trimmed-down example of the input data
which causes the unexpected output.  If you don't mind, extract
from your pickle files sublists of, say, five or ten elements,
change the code to set masterList and skipFreqList directly to
those sublists and verify that the problem still occurs, and post
that, along with what output you see and what output you expect.
