hi, when i have changed the path as the instruction tells, and then entered in sac, the terminal told me this : " dyld: Library not loaded: /usr/X11/lib/libSM.6.dylib Referenced from: /usr/local/sac/bin/sac Reason: image not found Trace/BPT trap: 5 " Could you please tell me what is wrong with it ?

I want to test the basic algorithms of another program that reads only CSS-format data from arrays. Hence I generated a set of impulses in SAC and tried to write them to a CSS-format file with "writecss". This failed with ERROR 1385: No worksets in memory. The traces look OK with "p1", which I assume means that they are "in memory". I tried to write the same set of impulses into an IMS (GSE) file with "writegse" (because I could convert this format to CSS with another program) but this c... [more]
