Geometry definition for Neuropixels probes | ||
The definition here are all from Jennifer Colonell | ||
See: | ||
https://github.com/jenniferColonell/SGLXMetaToCoords/blob/main/SGLXMetaToCoords.py | ||
A better approach is to pip install and use as a package | ||
Unfortunately, the GitHub repo above is not yet packaged and pip installable | ||
Better yet, full integration with ProbeInterface and the probes' geometry | ||
from Jennifer Colonell - this is in the making! | ||
