Electrode bank in neuropixels

[PSY-Yibo]

Hi -- We have some data from Neuropixels by Open Ephys. How can I get which Electrode bank I recode? Can I get it from the recording binary format data containing continuous, events, and spikes data? Or, whether I can only save it when setting the parameters in Neuropixels PXI Plugins as the photo.

Hi there! The electrode bank is stored in the settings.xml file which is saved along with each recording. Each probe has a section named NP_PROBE, which contains a CHANNELS entry that specifies the selected bank for each channel (with 0-based indexing on both banks and channel numbers).

You can also extract the electrode bank from the exported IMRO files.

The JSON files conform to the ProbeInterface specification, and only includes site geometry (not bank info).

Thank you so much! I get it.
