Dear SAC-help: I just downloaded rdseedv5.1 and tried to extract waveforms, response, and PZ files for a file from IRIS. I got the error and behavior mentioned below by Anne Deschamps. I have sac 101.5 installed (though the pre-release version), with linux opensuse 11.3, 64-bit. I do know that it only happens if you ask to produce polezero files -- for waveforms or response files, no error. The exit looks like this: ...

Dear Colleagues and Friends: With the new version of SAC 101.5, I have problems reading CSS files. I get the following error: *SAC> readcss 1523.wfdisc* *No wfdisc file(s) found in the specified directory* * ERROR 1301: No data files read in.* I must add that with the old versions of SAC I did not have this problem. Is this a bug? Thank you in advance. Alireza
