Thread: SAC plot problem

Coralie,

Soon after releasing 101.4 we found an error in sgftops.c. The error had
been there for a while, and it manifested itself only rarely so we figured
it could wait until the next release. It may or may not be related to
your symptom, but I am attaching a patch file that fixes it. I suggest
that you run the patch (or just edit sac/utils/sgftops.c as it is very
simple), compile it (one does not have to rebuild SAC), put the executable
in your path and see if it helps.

Let me know.
