Duplicate channels every 32 channels on OpenEphys GUI

[Barbara Coimbra]

Hi everyone,

I don't know if anyone else has encountered this issue recently, but at the moment (after updating the GUI to the recent version) whenever I connect an Intan headstage with 64 channels ( RHD2164), in the LFP viewer I can only get 32 channels duplicated (it is like a cycle of 32 channels).

In the acquisition board source the system detects 64 channels but it does not show nor records (only 32 channels duplicated.

However if I connect 2x 32 channels headstages, I can see the signal from both independently. I have tested this in 3 different setups (with an OpenEphys acquisition board) and the same happens (see attached figures - GUI and comparison of channels).

Any ideas on how to get my 64 channels back?

Thanks for any help!!

Hi Barbara,

Upgrading to the latest version of the Rhythm Plugins (v0.2.1, available via the GUI's Plugin Installer) should fix the problem.

Please let us know if you experience any other bugs or unexpected behavior!
