Hi, everyone, Recently, I need to post-process the data from the earthquake station, the SAC data file is stored in binary format, Do you know how to change the *.sac file to a non-binary format file? so that I can use my Fortran code read it directly. Thanks. Yueling

Hello everybody, I have read that there exists a set of Python functions which allow easy access to SAC files. After some extensive googling I have been unable to locate anything other than a mention in the following article: http://adsabs.harvard.edu/abs/2004AGUFM.S21A0273H Can someone please point me in the correct direction so that I don't spend time duplicating code? TIA Norman.

I read them and plot with limited Y axis. > r cev.x drp.x > ylim on -6e-3 6e-3 > plot1 If you look at the attached file, the first data is plotted with wrong axis limits. When I change the read sequence > r drp.x cev.x sac plots the first data (not the second or others) with the range of e+10 again. However, when the ylim is off, it is fine. On the other hand, there is no problem with the single plot command (plot). Is there a bug? I use sac v10... [more]

Dear Sac user's, I want to generate a plot of different files in only one plot, so I want to generate it in color to distinguish each file. I use P2, but I can´t remember what to write after that, to generate it in color. Can you help me, please? Thank you so much. María Yahoo! Cocina Encontra las mejores recetas con Yahoo!
