Zero Crossing Block

Script: Miscellaneous/


This Python ExternalAttrib script blocks a seismic trace between zero crossings. The block amplitude is determined by the min/max of the interval blocked.

The script requires the Numba Python package.


This example shows the attribute output (black wiggle) over the input (variable density). To get a blocky wiggle display interpolation has to be turned off in the 2D viewer properties.
