I modified the TMA_Metrics-full.csv to change the BDX column to be
BDX/BDW-DE and the BDW/BDW-DE column to be BDW. Doing this and then
applying a corresponding change to extract-tma-metrics.py (below)
created a perf json metric file that passed all the tests. I will
resend the generated files in a v2.
Thanks,
Ian
