reading Binary recording files

[lihao881230]

Hello, does anyone know how to read recordings in .bin files? We use the WhiteMatter acquisition system that records using the OpenEphys GUI.

We are working on a white matter recording extractor. The pilot version is here cc @pauladkisson ? Any comments here for white matter?

Not sure if the openephys guy transforms the data. We also have an openephy reader too which can be obtained with from spikeinterface.extractors import read_ophenephys. If that doesn't work we also allow people to load a binary file themself using

from spikeinterface.extractors import read_binary

But in this case you need to supply dtype, n_channels, and sampling_frequency.

I do believe the white matter recording extractor should work in this case. But let me know if you run into any problems.

Thank you for your response—the recording extractor is working without any issues. Do you happen to have an extractor available for the analog event channels as well (also in .bin format)? Or would it be best for me to load the event data manually using read_binary and compute the relevant event times myself? Thanks again for your help!

Hi, are the events also produced by the WhiteMatter? Are the signals multiplexed? Do you have access to the spec for the analog/events format?

Yes, at the moment you loading the data would be the simplest solution. I assume you want to load the data and then threshold it to extract event times, right?
