Plotting SpikeGadgets data from .rec file

[Muthu-Jeyanthi]

[neurotic] WARNING: Removing plot with channel name "MCU_Din1" because channel was not found in blk!
This is the warning while trying to plot DIO signal in the .rec file even though the channel id matches the id in trodes configuration file.

Is there a way to mention device name too under plots in metadata? Could that be causing the warning?

Also, are there any examples of visualizing data from .rec files in Neurotic?

Hi @Muthu-Jeyanthi,

The short answer is: no and no (or, more optimistically, not yet and not yet!).

What versions of Neo and ephyviewer are you using with neurotic?

Neo 0.10.0 was released about a month ago. I think the SpikeGadgets reader was first released with Neo 0.10.0, so I'm guessing you already have it installed.

Neo 0.10.0 introduced some changes that may have broken the latest release of ephyviewer. @samuelgarcia has started a compatibility fix (NeuralEnsemble/ephyviewer#151), and is close to releasing it (NeuralEnsemble/ephyviewer#154). I hope to find the time to help him in the coming days, but I've been really busy... (Sorry Sam!)

ephyviewer provides a file visualizer in the form of a command line interface. Perhaps you can plot your SpikeGadgets data using the following:

1. Install Neo 0.10.0 if necessary: pip install -U neo
2. Install the latest, unreleased ephyviewer, with the compatibility fix: pip install -U git+https://github.com/NeuralEnsemble/ephyviewer.git
3. Launch ephyviewer via the command line interface: ephyviewer

I was able to get this to work using the sample SpikeGadgets data available here.

On top of all this, neurotic is very likely to need a compatibility update too, but that will need to come after the release of the ephyviewer fix.

Yes exactly.
neo 0.10.0 introduce spikegadet.
current release of ephyviewer is not working with this neo.
If you install ephyviewer from source it should work but we still have some bugs in the master so maybe it is not perfectly stable.

I don't think I will have time to release properlly ephyviewer.

Make a brutal release could be an option but I would prefer to make a good one (with unit test passing on GH actions)
