Incorrect AP gain for probeType 2013 (4 shank 2.0)?

[guptadivyansh]

The AP gain for 2.0 probes is hardcoded here to be 80 for probe types 21 and 24. However, the manual for commercial 2.0 says the Gain is 100, and I also see that imChan0apGain=100 in my recordings with imDatPrb_type=2013.

Did the gain change between the test and commercial versions?

Yes, the gain changed between the test and commercial versions. I need to update the Datafile tools, thank you for the reminder!

Thanks for the quick reply!

Is it safe to rely on meta['imChan0apGain'] across 2.0 probe types? I'm fixing a similar issue in spikeinterface/neo

[jenniferColonell]

Yes, for any new data, you can use that metadata item. I’ll add that to Datafile tools, too – but I also need to keep them backward compatible.
