Hello,<br><br>I have 2 SAC-related queries that are causing me problems on a couple of fairly urgent projects currently:<br><br>i) I inherited a Matlab program for surface wave analysis. The seismogram files that it reads are in PITSA ASCII format. Is there any existing software to convert standard SAC to PITSA ASCII? Or will I have to convert SAC binary to alpha, and try to reformat the resulting ascii files?<br>
<br>ii) Another inheritance: this time I have been given the source code (fortran) for John VanDecar's "mccc" multi-channel cross-correlation program. The program contains a lot of SAC functions, such as "rsach", "getnhv", "rsac1", "getkhv", "getfhv", "setfhv", "setkhv", "wsac0"... (and probably a few others I haven't spotted yet). Along with the Fortran codes I was given a couple of SAC libraries of the type "libsac.a". The problem is that this set worked OK for a SUN system, but I am on Linux (CentOS 5). With the SAC library that I was given, and the SAC library I obtained when downloading SAC executables for my current system, I was unable to compile the code. I have a really old SAC library (old enough that I can't remember even which version it comes from) and that one allowed mccc to compile... but not to run (segmentation fault). Can anyone advise me on using SAC libraries correctly and/or making changes to the fortran code that will allow me to run this program?<br>
<br>I should add that I'm a rather poor programmer - just about literate in Fortran, okay in simple shell scripts, but not too great with any other programming languages! Any advice greatly appreciated.<br><br>Thanks a lot,<br>
