The conic command is actually an alias that uses pdbrun to send data to the outside program conic. There are many options, which are detailed in the conic manual page.
*On Mac systems, the conic -o flag or configuration file output option must be used to generate any output at all. If display is desired in addition to an output file, the -s flag should also be used.
