Hello everyone,
I have a time series of synthetic traces and would like to convert them to
SAC format. I know I could use the CONVERT function but before that I have
to format the ASCII (time series) file by arranging the values for sac
header. Is there a utility to do this pre-formatting before I could use the
CONVERT function?
ex. I believe my ASCII file should look like the following before using
CONVERT

You do not have to construct a SAC header from scratch. SAC has
subroutines that can be called in C or Fortran programs that put things in
the right place. In SAC, enter
SAC> help tutorial
and read the section on reading and writing data files.

We've developed a python package called obspy
(http://svn.geophysik.uni-muenchen.de/trac/obspy) that allows you
creating SAC-files from a raw timeseries in python.
Cheers,

Dear Manuka,
Again the most convenient way I've found to perform conversions between ascii and binary sacfiles is to use the subroutines contained in the module sac_i_o that comes with the fortran program sac2xy and that you can download from the following webpage :
http://web.utah.edu/thorne/software.html

Pierre
