GSESEI, converts from GSE1 and GSE to and from SEISAN
Note: From version 7.2, extract should be used instead of gsesei.
This program is a modified version of the GSE conversion program CODECO, which is written
by Urs Kradolfer and part of AutoDRM. It converts waveform data between SEISAN binary,
GSE1 and GSE2 formats.
The different output formats will be displayed on the screen. Multi channel files are supported
in both formats. When converting from SEISAN to GSE, response information from the trace
header can be converted to GSE and output filenames will be as described in the section
‘gseresp’. The start time of station operation is used by SEISAN for instrument correction (see
RESP program), but not given in the trace header and therefore set to 1950.
GSE output filenames are made by adding the output format to the input filename. SEISAN
output files get the SEISAN standard waveform filenames.
Known bugs: It seems that there is a bug in the conversion of the INT and INTn format. There
is also a problem with reading the CM6 format.

GURSEI, Güralp to SEISAN
Converts Güralp GCF files to SEISAN format, only works with one channel data. Maximum
number of samples as defined in seisan, at least 500 000, channels codes can be defined
using the gursei.def definition file. If no definition file, the station name is GURAL and the
component is taken the gcf header.

GSERESP, conversion between GSE and SEISAN response files
The program provides conversion between SEISAN, GSE1 and GSE2 response files. The
response can be given in frequency, amplitude and phase (FAP) triplets or in poles and zeros
(PAZ). Since the number of values in the GSE format is unlimited the conversion from SEISAN
to GSE only changes the format, whereas converting from GSE to SEISAN, if the number of
FAP triplets is more than 30 or the number of poles and zeros larger than 37, the response in
SEISAN format will be approximated by 30 FAP triplets. The output files in SEISAN format will
have the default SEISAN response filenames (see RESP program and SEISAN response
format). Output files in GSE format will include the station name, the component, number 1 or
2 for GSE1 and GSE2 respectively and end on ‘.CAL’ (e.g. MOR_SHZ2.CAL (GSE2),
KONO_BZ_1.CAL (GSE1).
