I have a similar question, and David Horvath has kindly enlightened me to the “add” resnucl e plot option. When I try to plot my .dat file, my flair seems to stop working, and I need to kill it from the command line. I have attached working flair file here for testing.
Thanks @sunil@rick for reporting
I’ve found the bug and it is fixed.
You can find the corrected version 3.0-3 in the usual location or better using the flair repository.
