SUMMARY
Controls errors due to bad cut parameters.
SYNTAX
CUTERR FATAL|USEBE|FILLZ
INPUT
FATAL: Treat cut errors as fatal. USEBE: Replace bad start cut with file begin and bad stop cut with file end. FILLZ: Fill with zeros before file begin or after file end to account for difference between bad cut and file begin and end.
DEFAULT VALUES
FILLZ for signal stacking subprocess, USEBE for others.
DESCRIPTION
This command controls error conditions arising from bad cut parameters. These error conditions can be defined as fatal errors (FATAL). If the starting or ending cut parameter is undefined in the header record the disk file beginning or ending value can be chosen (USEBE). If the cut parameter is defined but the resulting cut value is less than the disk beginning value or greater than the disk ending value, the beginning or ending values can be used, or enough zeros can be added before or after the actual data to make up the difference (FILLZ).
EXAMPLES
Assume that FILE1 has a begin time, B, of 25 seconds, a first arrival, A, of 40 seconds, and a sampling rate of 100 samples per second. Assume the following commands were typed:
u: CUT A -20 E u: READ FILE1The starting cut evaluates to 20 seconds and generates a bad cut error condition. In the USEBE mode, the starting value would become 25 seconds (B). In the FILLZ mode, 500 zeros (5 seconds at 100 samples per second) would be inserted before the data and the starting value would remain as 20 seconds.
