Yes, e.g. to obtain the name of the nets with probes:
probes = geGetAllProbe()
probe_types = probes ~>probeType
nets = probes~>pathObjectName
And then you can use function geGetAdjustedPath(win net_name) to obtain the name of the the net with net_name at the highest level of hierarchy. If two nets have the same root net, they are the same net.
