Could we get (Matched edge index,indices) via command line approach

[treerapot1]

Since my case have to run st_match via commandline (use --omp) due to huge gps data.
i want to map timestamp of opath to cpath.
i saw that we can get the index from python api (getting field "indices") as follows:

• print "Matched edge index ",list(result.indices)
  So, i try to put "indices" as the field in output_fields in commandline but i can not the indices return as follows:
• stamtch --network..... --gps..... --output.... -- output_fields opath,cpath,indices --use_omp
  So Could we get (Matched edge index,indices) via command line approach, please?
