Dear SAC users,

does anybody knows how to make colour filled seismograms? Say, positive
values filled with red and negative with white or some other colour...

Best regards and thanks in advance,

Aderson

    You can use GMT to do it. Look at function pswiggle. You have to run the program twice, once for + wiggles (red) and once for - wiggles (blue). I usually convert .SAC to required format using matlab routines of Mike Thorne (rsac.m and lh.m): http://web.utah.edu/thorne/software.html

    There is an active thread on pssac.c written by Lupei Zhu in this list, which you can follow.

    You can use the pswigb or pswigp in the CWP/SU:Seismic Un*x (SU) package.

    Dear All -

    MacSAC implements the command LINE FILL RED/GREEN that does this for every waveform display in SAC (screen, sgf, ...).
