    Matthew,

    The sacio library basically only allows one to read and write sac files.
    There are future plans to allow access to features such as
    filtering, but not at the present time.

    I would suggest writing a shell script, perl script or python script to
    comunicate with sac at the present time.

    Cheers,
    Brian

    That was a very quick reply - thanks

    But is filtering possible with fortran?

    regards,

    Hi everyone again,


    does anyone has a working c program that reads and writes a SAC file. I
    am taking the sample code from the SAC website
    http://www.iris.edu/manuals/sac/manual.html and i have the sacio.a file
    but all in vain.

    Do i need to expand sacio.a ?? in which directory??
    DO i need to #include any files?? or set some environment???

    hope i get some reply


    Matthew

    First of all i would like to thank this group for the immediate replies.
    I dont know if it is a big group but it sounds active :)

    Thanks for your code. I managed to create my own code using the sacio.a
    file. ALso i followed the steps found on the online manual which most of
    which worked. Those which did not work have a most probable reason that
    i did something wrong :) - but i got what i wanted.

    I guess the code you sent me is something similar to the sacio.

    Thanks for all your immediate support and help.

    regards,

    Matthew

    If you want to read and write C code you dont need sacio.a or sac.a.
    These include only fortran routines (But as Brian Savage said that
    may change with SAC2000). In C all you need is two lines of code to
    read and write sac files. The binary format is a simple data
    structure of mixed integers, floats, and strings all defined in sac.h.

    Try this sample C codes as templates.


    Include files YES use sac.h
    Environmental variables NO none needed.

    Good luck,
