picrestore - BSU restore picks made on data reduced by a correctional velocity
picrestore bredxxxx.dat bredxxxx.pic >out.pic
Basic Seismic Utilities (BSU) restores picks made on a correctional velocity reduced data set. Example: bref.f run on a xxxx.seg data set to shift data into approximate flat alignment with a reduction velocity. Octave program, segpic.m would then be run, and the saved pick file, bredxxxx.pic is the second argument to picrestore. The first argument is an output file from bred.f, called bredxxxx.dat, where the xxxx is a place holder here for the actual input file first 4 characters. Output written to standard out (redirect to out.pic)
Options
(first and second arguments are required)
bredxxxx.dat
The output file from bred.f contains time shifts and trace numbers
bredxxxx.pic
The output from BSU segpic.m program (run in Octave)
NOTE:
If invoked with no options, will give USAGE: statement
EXAMPLE:
Assume a file to be picked is s200.seg, and data are
approximately flattened with bred. Octave run of segpic.m
produces output of (tr,pic) in breds200.pic
picrestore breds200.dat breds200.pic >out.pic
The pics file, breds200.pic is adjusted by the shifts in breds200.dat (produced when bred.f was run on a file s200.seg). Restored picks redirected to file out.pic. Then run bpic to insert picks into original file s200.seg
bpic s200.seg 1 out.pic 0.0
File bpics200.seg now has pics in headers, and can be renamed as original s200.seg
