Hi Donna Thank you, this format worked perfectly. I misinterpreted the documentation to mean that, if you didn't specify label names in the list that the default behavior of -metric-label-import would be to generate a name of "Label_#" for that label value, as opposed to if the program encounters a label that is not included in the already correctly formatted list -- obviously now my original list had been incorrectly formatted.
Anyways, thanks!
