Binary dat files to Plexon Offline sorter about analysis-tools HOT 7 OPEN

I would recommend checking out Neo...it's been updated to support the latest OE Binary format, and I assume the PlexonIO class is compatible with Offline Sorter. But you'll have to test it and see.

great I'll take a look!

@guilhemibos @jsiegle Hello, are you aware of a good way to use Plexon Offline Sorter with the OpenEphys binary data now?

I believe it's possible to load the .dat files (sometimes called .bin files) directly into Offline Sorter, but I haven't actually tried this myself. Does the Offline Sorter documentation mention anything about this? Note that this would just be the raw continuous data, and not the detected spikes (which are stored as .npy files).

Hello Josh, unfortunately though the Offline Sorter manual mentions being able to load continuous data, there isn't enough details or explanations on the best ways to deal with this. Are you aware of other resources used by the Open Ephys community for spike sorting, or if this has been discussed in other threads?

I gave up trying to use Plexon's offline sorter, it does not seem adapted. Instead, I'm using Kilosort 2 (best for the type of probes I use than KS3).
If I had to try again Plexon OS, I would split my continuous.dat file in as many channels that I have and try with that...

For anyone interested, I kinda found a cheat to make this work - I start with picking only the 4 channels for each tetrode from the OpenEphys continuous .dat files, and saving their timeseries as a .mat file. I then load it into the Plexon Offline Sorter (OS), and export it as a new .plx file. Then load this .plx file into OS again, and under the 'channels map', choose tetrode instead of single - these 4 channels are then saved as one tetrode and can then be sorted as needed.
