Command Syntax



Commands consist of one or more required keywords followed by optional key/value parameters. For any key/value parameters that are not specified, the parameter values will be set to the values from any previous invocation of the command, otherwise to default values.

The command syntax is shown in brackets [...] in the message window when a command is invoked from the command line or through the graphical user interface.

Multiple commands can be entered on one line, the commands must be separated by a comma (,) or a semi-colon (;). Substitution with trace header values is performed for argument values prefixed with &, e.g. &dist is replaced with the numeric distance in km. Substitution is attempted first from the SeisGram2K trace header, then from the original data file header. To force substitution with header values from the original data file header, prefixed with &&, e.g. &&USER1. Substitution is case dependent.

The command syntax is similar to, but not always identical to, the SAC command syntax, when a corresponding SAC command exists.

<group_index> is an absolute (0...N) or relative (+n or -n) trave group index.
