Central repository of .prb files

[Max Hunter]

Dear all,

I've created a central open-source repository at https://github.com/kwikteam/probes/ to contain probe files from different manufacturers. Please contribute your own!

In future phy will have an option to download this repository automatically and keep a local copy (so new probes/manufacturers will be added as they come out, and you can just specify the probe name in the .prm file), but for the moment, I would really appreciate any contributions you all have - at the moment Justin Kiggins has very kindly contributed an automatically generated set of all the NeuroNexus linear probes (1028 of them!) but if anyone has any .prb files from other manufacturers, we'd really appreciate your contribution!

If you're unsure of how to make a GitHub pull request, please drop me a message and I can help or include them directly myself.

A note from Justin about the NN probes:

"these are the probes in the nn database labeled "linear". I think some are actually custom, however, and are not accurate. further, I couldn't parse the logic for tetrodes or poly-trodes."

A discussion on automatically generating probe files is here: https://github.com/kwikteam/phy/pull/521.

In the future, we will probably have an option to generate the connectivity graphs automatically (see http://www.justinkiggins.com/blog/generating-channel-graphs-for-klustakwik-automatically/) but in any case, the geometries will still be manually needed - if possible please specify these in microns so generating the connectivity graphs will be easier (and so other algorithms which need the physical probe dimensions can take advantage of the same probe files)

Best,

Max

Dear Max,

Thanks for the valuable work.

I am trying to make sense of the probe files and make sure its what I need. As an example if we look at A1x32-7mm-100-1250-A32.prb, based on the defined geometry in this file it seems like if the probe sites are aligned from 1-32 along the shank, while it is not the case if we look at Neuronexus site mappings:http://neuronexus.com/images/Electrode%20Site%20Map/A32Maps_2013_11_22.pdf

Where  does the discrepancy come from? 

Best regards,

Vahid
