This is the earthworm global phase picker intended for use with glass. It is based on Ray Buland's fortran originally developed in the early 1980's. Its unpublished and the details on how it works are left as an exercise for the enterprising student.
Example configuration file raypicker.d:
#
# Configuration File for raypicker
#
MyModId MOD_RAYPICKER # Module Name
InRing WAVE_RING # Transport ring from which to get waveform data
OutRing PICK_RING # Transport ring to which to write output
HeartBeatInterval 60 # Heartbeat interval, in seconds,
# WARNING: Heartbeat interval is also used to check on thread status;
# No NOT MAKE THIS NUMBER SMALLER THAN THE TIME IT TAKES TO
# PROCESS A MESSAGE OR THE PROGRAM WILL CONSTANTLY RESTART!!!
# (default min: 15 secs)

MaxSampleRate 101.0 # Maximum sampling rate (default: 101 Hz-
# NB: make this slightly larger than desired, ie.
# 101 Hz for 100 Hz data, to allow for minimal
# tolerance in floating point comparisons in code)

QueueSize 500 # Max number of messages to queue (default: 500)
MaxPreFilters 20 # Max no of prefilters to allow (need at least 2xnumber of different
# sampling rates of data expected - one for BB data and one for
# data SP; default = 20)
