We are very close to coming out with SAC 101.4. Prompted in part by a recent exchange on this listserv about calculating traveltimes in SAC, I looked at the SAC traveltime command.

Greetings all, I have a bunch of .sac files that I saved in labview and I can't seem to open them in SAC. It says that when labview saves files as .sac they are readable in SAC. Am I missing something here? I am using SAC Version 101.3b. The error looks like this: SAC> r *.sac arg_1.sac arg_2.sac arg_3.sac arg_4.sac arg_5.sac arg_6.sac argln2.sac argln3.sac argln.sac cool_1.sac heated_1.sac march1.sac march2.sac march3.sac march4.sac march5.sac march6.sac march7.sac noargln2.sac noargln.sac ...

Hi, I am using the LIBSAC libraries to read header values into a fortran code. I am having trouble reading in the 'dist' header field. The rsac call in the fortran code does not return an error, as other header values can be read. The call to get the 'dist' header value is: call getfhv('dist',dist,nerr) But when running on a sac file, I get an error saying that the field is undefined... ERROR 1336: Undefined header field value. dist However, when I use sac and open this same file and list... [more]

Hi, SAC subroutines always show the error message when the header is not defined in the sac files. But I wrote down my options if there is no header info, it will do something else. Is there any way I can turn off the error ( not warning) message? Thank you so much!
