wftimeshifter reads waveform data (compressed or uncompressed) from one transport ring and writes it to another ring, adding an offset to starttime and endtime. The module is intended to accomodate low-jitter, high-latency analog telemetry.
# wftimeshifter configuration file
# Basic Earthworm setup:
#-----------------------
MyModuleId MOD_WFTIMESHIFTER # module id for this instance of wftimefilter
InRing SCNL_RING # shared memory ring for input
OutRing WAVE_RING # shared memory ring for output
HeartbeatInt 30 # seconds between heartbeats to statmgr
LogFile 1 # 0 log to stderr/stdout only
# 1 log to stderr/stdout and to disk file
# 2 log to disk file only
# List the message logos to grab from InRing, WILDCARDs permitted.
# Multiple "GetLogo" commands are allowed, with no hardcoded limit.
# The four valid message types are:
# TYPE_TRACEBUF, TYPE_TRACEBUF2, TYPE_TRACE_COMP_UA, TYPE_TRACE2_COMP_UA
# Installation Module Message Types
#-----------------------------------------------------------------
GetLogo INST_WILDCARD MOD_WILDCARD TYPE_TRACEBUF2
MaxMessageSize 4096 # length (bytes) of largest msg to be processed
# List the SCNLs to grab from InRing, WILDCARDs permitted.
# Multiple "Offset_scnl" commands are allowed, with no hardcoded limit.
# If wildcards are present, the list will be searched top to bottom with
# the first match being applied. If no wildcards are present, the list
# will be sorted and a more efficient binary search used.
