Hi, Could someone please tell me how I could retrieve amplitude at a user defined time in a SAC file and read it into memory using SETBB? Sounds easy but I couldn't find a way to do it. MARKVALUE gives you time stamps and not amplitude. Thanks !

Sac’s ‘saveimg’ command produces some very nice looking plots. It works very nicely with trace plots I create with the ‘plot1' sac command. But, I recently tried it out with some particle motion plots generated by the ‘plotpm’ sac command. Although an x-windows 'plotpm’ plot is visible on my screen when I use the ‘saveimg’ command, the .pdf file plot shows only the first segment of the original plotpm plot (it seems to be the line segment between the first and second data points). And a .ps... [more]
