SYNOPSIS

PERL PROGRAM NAME: susplit.pm

AUTHOR: Juan Lorenzo (Perl module only)

DATE: V0.2 6.19.23

DESCRIPTION:

Version:

USE

NOTES

There are now four cases that susplit can handle:

1. As in the traditional case, the split files are written to 
the directory in which perl thinks the code is running.

2. If a list of su_base_file_names is given (in $DATA_SEISMIC_TXT)
split files are written to $DATA_SEISMIC_SU.

3. If an su_base_file_name is given then the split files are written
to $DATA_SEISMIC_SU.

4. Cases 2 and 3 are mutually exclusive and a warning message is given.

Examples

SYNOPSIS

SEISMIC UNIX NOTES SUSPLIT - Split traces into different output files by keyword value

     susplit <stdin >stdout [options]					

 Required Parameters:							

	none								

 Optional Parameters:							

	key=cdp		Key header word to split on (see segy.h)	

	stem=split_	Stem name for output files			

	middle=key	middle of name of output files			

	suffix=.su	Suffix for output files				

	numlength=7	Length of numeric part of filename		

	verbose=0	=1 to echo filenames, etc.			

	close=1		=1 to close files before opening new ones	


 Notes:								

 The most efficient way to use this program is to presort the input data

 into common keyword gathers, prior to using susplit.			"


 Use "suputgthr" to put SU data into SU data directory format.

CHANGES and their DATES

V0.0.2 06.13.23

Normally susplit writes divided files into the local directory. Now, split files are automatically moved into $the DATA_SEISMICS_SU directory.

Normally, susplit input consists of a single file. Now, user can enter the name of a list containing more than one file. Now, susplit will iterate over each file with the same general instructions.

Now, there is no need to use a data_in or data_out module. Now, susplit handles input and output internally.
