Dear all I am working with the SSS subroutine, and after saving the file using the WRITESTACK command, I'm trying to convert the output file using sacdump (the final idea is to get a two column time / value file). However, sacdump shows the next error message [file.sac] Unrecognized format (not SAC?) Error parsing file.sac Anyone knows if the output format coming from SSS is a .SAC format? Or anyone had the same problem before? thanks in advance Claudia Pavez
