Sending TTL w/ Binary Format #1

Closed markschatza closed 3 years ago

markschatza commented 4 years ago

Hello!

I added the TTL functionality awhile ago. It seems that it isn't working with Binary file format or with the new record node. Not sure if it's a network events issue or a binary format issue. The message events are going through, but the TTL events are not being triggered.

This is likely related to an issue with the underlying Record Node connections that we're in the process of fixing. @medengineer, can you test out this use case?

jsiegle commented 3 years ago

This should be fixed in the latest test binaries: https://dl.bintray.com/open-ephys-gui/Test/

Can you check if it's working now?

I don't think so? I used v0.5 and then used the plugin installer to install network events. I then sent ttl events over (which show up in the message area in the plugin gui). When I load in the structure.oebin file through load_open_ephys_binary I get the correct number of events. But the channelindex is 1 for all of them so I think they are just mesage events, but not the ttls. I'm sending one ttl event to each of the 8 channels.

Hi Mark,

Are you using a similar chain as below? It should also work with a NetworkEvents module going into a Record Node by itself.

Oh I see. Yep, I get exactly that. My problem was I didn't understand exactly how to use the load_open_ephys_binary() function. I wasn't changing the index based on my signal chain. Updated the index and works great.

Thanks for clarifying! :)
