Crash on recording #15

Open juliencarponcy opened 3 years ago

juliencarponcy commented 3 years ago

Hi,

Just experienced repeated crashes, only when recording, was a test so nothing bad. After testing multiple things, I would bet this is when you try to record with Record Events and Record Spikes option ON (as it is for default). It might not be a PXI specific issue though. I would maybe suggest to check whether you have actual events or spike threshold defined and on the contrary, do not allow to tick these options on the record node. I'm just starting back with the neuropixels and open ephys, I guess I will be able to tell you more later. I'm still recording now. Also, don't know if the behavior is planned, but recording in the open ephys format do not seem to work with the neuropixels. That's unfortunate, I like this format ! Finally, I was wondering if there is a saved log of the debug console somewhere so i could pass you more reliable information,

Thanks very much,

Julien

Hi Julien,

First of all—are you using the latest version 0.5.2.1? We recently fixed some bugs in the Record Node that could explain the crashes.

If you are using the latest version, what's your signal chain? We'll try to replicate the problem on our end.

The Open Ephys format is not compatible with Neuropixels probes, because there are problems opening >200 files simultaneously. Therefore, you need to use the Binary format, which stores all the channels in one file. We will add a warning to the Record Node if the Open Ephys format is selected in cases where the channel count is too high.

We are planning to add a saved log of the debug console in an upcoming release, so that should be available soon.
