Recordings from SpikeGadgets hardware have two possible channel maps: HWChan (a channel map defined by the amplifier) and Trodes channel map (for displaying on Trodes, the data acquisition software for SpikeGadgets). Both of these are in the header of the file that contains the recording (in .rec format). The channel IDs one gets with get_channel_ids from a SpikeGadgetsRecordingExtractor is in the Trodes order, which is sensible. But the order of the traces is completely scrambled (neither Trodes nor HWChan). Seems like this recording extractor relies on neo. @samuelgarcia @alejoe91 Could you take a look?
