Loading Axion Biosystems AXIS data

[alexmascension]

Hi!

Does spikeinterface support loading .raw or .spk formats of AXIS data? I don't see it in the docs, so I guess this format is not implemented.

Thanks!

Hi @alexmascension Neo does not support this format as far as I can see. Feel free to open a PR to add a corresponding IO to Neo, see the instructions for adding a new format.
As far as I know spikeinterface does not use Neo to load spiking data, so for the .spk files you will need to check with that project directly.

Hi @JuliaSprenger, I'm using the SpikeInterface module to do the loading, so I'm not sure if I'd be able to do the PR. I was redirected by @alejoe91 to open the issue here.

@alexmascension do you know if there is a Python API to open Axion data?

[alexmascension]

I can't find it. They currently work with MATLAB files to load the data. I will try to contact them to see if they have some Python code for that (although I guess they won't).

In my lab someone have also this system.
Apparently the raw is a standard binary file, so you must specify manually the number of channel the sampling rate et the dtype.
In my case it was dtype=int16 8*64=512channels and sampling_rate = 12.5kHz.
I did not find any header in txt, json or xml format along sie the raw file.
I need to check with my colleague.

I ended up creating some scripts that do the job (you can find them here), although I guess that a better implementation can be done.
