mwap_engine db [-phase phase -sift expression -pf pfname]
mwap_engine is the actual program that does multiwavelet array processing as described in mwap(1). The mwap command actually is a TCL/TK GUI that simplies interaction with mwap_engine. mwap and mwap_engine interact through two named pipes defined in the input parameter file for mwap. mwap_engine accesses this same parameter file. i.e. mwap_engine by default reads the mwap.pf parameter file. This means basically that mwap and mwap_engine have overlapping parameter spaces. You can specify an alternative parameter file for mwap_engine through the -pf argument.
-phase is used to use arrivals other than the default P phase.
-sift is used to apply a selection criterion to the input view before processing begins. The associated expression is passed verbatim to dbsubset to produce a new subset view. Because mwap_engine sorts data by evid the most commmon use of this argument would be to start processing at a particular evid (e.g. -sift "evid>=275" will start with evid 275).
-pf allows using an alternative parameter file to the default mwap.pf.
