Hi, more information would be helpful. Is this error seen when executing crts_controller or crts_cognitive_radio? What is the output before this error e.g. does the crts_cognitive_radio receive the scenario parameters before this error occurs or is this literally the only output you're seeing?

That said, I logged into CORNET, did a fresh clone of the repo, and I'm seeing issues related to the UHD drivers when I try to run crts_cognitive_radio. I'm assuming something was updated on the CORNET servers which broke some of the calls we've used in the CRTS code. Perhaps this is the same issue you're seeing although I'm not seeing the same error signature as you. I'll look into updating the UHD API calls shortly.

the error seen when executing crts_cognitive_radio and I only see **node parameters** which are defined in scenario configuration file.[1]

I tried to clone and recompile crts and now it works fine.

Yeah, my issue went away when I rebuilt on a different node. It looks like nodes 7001 and 7002 have the USRP X300 on them, I'm wondering if someone is messing around with the UHD software on these nodes. Anyways, not going to worry about this unless there's a problem on nodes with the typical setup.
