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".
