bmrg - BSU program which merges traces from many files into one file
bmrg [ -h | pfix | iffile | ilfile | ifinc | iftrc | iltrc ]
Basic Seismic Utilities (BSU) program which merges traces from many files into a single file. It is assumed that the set of files to be merged fit a pattern with an alpha-numeric prefix (constant) followed by numeric sequence number (1 to 4 digits). Note that the prefix must include all characters which are constant in the pattern to be merged. One may wish to run a header dump (bdump) on a merged file to confirm that the correct traces have been collected.
Options
|
-h |
Online help giving details on command line arguments | ||
|
pfix |
Alpha-numeric prefix which is constant (up to 40 char) |
NOTE: length of
pfix = number of invarient characters in file names
Ex. If file names run s001 to s090 then pfix=s0
Ex. If file names run s001 to s132 then pfix=s
|
iffile |
First file sequence number (1 to 4 digits) |
EXAMPLE: If first file is s001.seg, then enter 001 for iffile
|
ilfile |
Last file sequence number (1 to 4 digits) | ||
|
ifinc |
Increment for sequence numbers. 1=every file, 2=every other file, etc. | ||
|
iftrc |
First trace number in each file to include in the merge. | ||
|
iltrc |
Last trace number in each file to include. Traces iftrc to iltrc are merged. |
NOTE:
If invoked with no options, will prompt user for input
parameters.
EXAMPLE
bmrg w0 1 10 1 2 4
To merge traces 2 through 4 on files w001.seg through w010.seg.
bmrg.seg
The output file is always named bmrg.seg
standard output
produces a progress bar
bmrg.lst
Echo check of input parameters and list of file names merged.
