SUMAX - get trace by trace local/global maxima, minima, or absolute maximum

sumax <stdin >stdout [optional parameters]

Required parameters:
none

Optional parameters:
output=ascii write ascii data to outpar
=binary for binary floats to stdout
=segy for SEGY traces to stdout

mode=maxmin output both minima and maxima
=max maxima only
=min minima only
=abs absolute maxima only

verbose=0 writes global quantities to outpar
=1 trace number, values, sample location

outpar=/dev/tty output parameter file; contains output
from verbose

Examples:
For global max and min values: sumax < segy_data
For local and global max and min values: sumax < segy_data verbose=1
To plot values specified by mode:
sumax < segy_data output=binary mode=modeval | xgraph n=npairs
To plot seismic data with the only values nonzero being those specified
by mode=modeval:
sumax < segy_data output=segy mode=modeval | suxwigb

Note: while traces are counted from 1, sample values are counted from 0.
Also, if multiple min, max, or abs max values exist on a trace,
only the first one is captured.
