"""Collect rasters of responses for all LGN opto experiments as a function of stimulus type
(movies, gratings), run state, and opto state. Then, calculate various measures and save
results to DataFrames. Some variables (DataFrames and mseu string lists) can be optionally
saved to and loaded from .pickle files to avoid long and unnecessary recalculation times.

Run this script at the IPython/Jupyter command line; the `-i` runs scripts in IPython's
namespace instead of an empty one:

`run -i main.py`

`pvmvis` (default), `ntsrmvis` or `negntsrmvis` can be provided as an `--exptype=` argument
to this script, to load and later plot PV-Cre (most of the paper), Ntsr1-Cre (Fig1S4),
or Ntsr negative (Fig1S5) data, respectively.
