To be able to make sense of the data from the probe, we need to reordered the channels so that the channels from a shanks are grouped together from the highest to the lowest recording site on the shank. This is needed for visualisation (when looking at the oscilloscope) and for spike extraction.
The ordering of the channels is a 2 step process.
- Determine the "Neuronexus" channel order that you would like to have. You should order them by shank number, from the top to the bottom.
- Create a dictionary to match Neuronexus probe channels to the Intan Amplifier channels.

The website does not have the order of channels for the 4x16 probes.
Channel index starts at 1.

The channel number in ktan are the same as the Intan amplifier. There are 16 digital inputs added to the analog input of the amplifier.
There is a python script for channel mapping for the H64LP probe.
