Error in storing TTL events (recordings in OpenEphys format)

[Anna Bertucci]

Hi all,
I am a Phd student who works at the university of Parma. Up until now, We conducted several experiments using the OE GUI for recordings. We had an Opal Kelly acquisition board and we were using version 0.4 of the guide. Recently, the board broke and we had to fix it and replace it with the most recent acquisition boards that use the new Open Ephys FPGA (instead of Opal Kelly). We encoutered two issues:

1. We tried to use the guide but the old version 0.4 couldn't detect the new acquisition board. Is there a way?
2. we then downloaded the newest version of the guide 0.67 (We usually record in openephys format, so i installed the necessary plug-in as explained in the docs) and now we could read the acquisition board, but there is another problem.
   I tried and performed a "fake" acquisition of an experiment, and everything seemed fine, until I realized that there is a problem with the Task Events: during the recording online, I can see that OE receives the different TTLs from the behavioural software that controls the task, but once the data is saved, and I try to open the .EVENT file, an error appear about the headers file. I opened as text the file and some informations, such as sample rate, buffersize,bitvolts they are nowhere to be found. I double-checked the signal chain to be sure everything was in place. Since I am not an expert, am I missing something?
   I hope I was clear enough, thank you in advance.
