Hi everyone,
I am trying to use the open ephys GUI with an Intan RHD2000 acquisition board and am having a problem.
As soon as I add the electrodes to the Spike detector module, the GUI crashes and gives a segmentation fault.
Rhythm FPGA updating settings.
Rhythm FPGA setting num outputs to 0
Bandpass Filter updating settings.
Spike Detector updating settings.
Adding electrode with 2 channels.
Segmentation fault (core dumped)
In searching for a solution, I found this note under the Analog input section on the open ephys website. (
https://open-ephys.atlassian.net/wiki/display/OEW/How+it+works)
"NOTE: The Intan RHD2000 Evaluation Board uses the AD7680 ADCs from Analog Devices. The control sequence for these chips is
not
directly compatible with the one used by the TI chips. Therefore, if
you want to use the Open Ephys acquisition board with Intan's software
(or Intan's board with the Open Ephys software), you'll have to exchange
the default FPGA bitfile in order for the ADCs to work."
However, this is not mentioned in the neural data acquisition section. I presume that since the neural acquisition AD converters are on the Intan headstages, it should be compatible without any adjustments if I am just trying to add neural data acquisition channels. Can anyone help me with this?
