[SAC-HELP] Multiple Questions

[Brian Savage]

Jesse,

Would you mind sending me a selection of sac files and commands for any set of commands you think is not working properly.

It appears that the first problem (waveforms not appearing) is a bug and needs fixing.

Saving multiple files to plots can be achieved with something like
SAC> read file1 file2 file3 file4
SAC> bd sgf
SAC> p1 p 1
Waiting
Waiting
Waiting
SAC>  ls *.sgf
f001.sgf	f002.sgf	f003.sgf	f004.sgf

This cannot currently be done with the saveimg command. This is something we need to consider.

Please let us know what version you are running.

Thanks
Brian
