\fBRead and manipulate miniSEED records\fP
|
|
.SH DESCRIPTION
|
|
.sp
|
|
scmssort reads unsorted (and possibly multiplexed) MiniSEED files and sorts
|
|
the individual records by time. This is useful e.g. for simulating data
|
|
acquisition and playbacks. Removing of duplicate data and trimming of time
|
|
window is available.
|
|
.sp
|
|
scmssort reads single files and output to the command line. Cat many files
|
|
to read them at the same time. In this way huge amount of data can be processed
|
|
efficiently.
|
|

Applications to miniSEED records:
|
|
.INDENT 0.0
|
|
.IP \(bu 2
|
|
Sort records by time, e.g., for playbacks.
|
|
.IP \(bu 2
|
|
Remove duplicate records from files and clean waveform archives.
|
|
.IP \(bu 2
|
|
Filter data records, i.e. keep or remove them, based on
|
|
.INDENT 2.0
|
|
.IP \(bu 2
|
|
time windows,
|
|
.IP \(bu 2
|
|
stream lists where each line has the format NET.STA.LOC.CHA including regular
|
|
expressions. Such stream lists can be generated, e.g., using \fI\%scinv\fP\&.

.IP \(bu 2
|
|
Combine with \fI\%scart\fP or \fI\%msrtsimul\fP to archive data or to make
|
|
playbacks with real\-time simulations.
|
|
.IP \(bu 2
|
|
Filter data by stream IDs using NSLC lists which can be generated using
|
|
\fI\%scinv\fP\&.
