In that directory, what do you get when you grep for the ++++? Or what is on line 26 of 1ca2_min.conf like the error message is telling you? I've never seen this before, so I suspect its something you added into your configuration file by mistake that is confusing the parser.

Hi everyone
I am trying run a MD simulation on namd (a single node operation on a supercomputer.) However, I keep getting the following two error messages:

The bash script that I am running is: ./dir/namd2 +p14 +setcpuaffiinity ./config
I am running the job in the same directory that my configuration file is in. How can I resolve this error?
Thanks
