RDSEED: convert seed to miniSEED

HI,

I am using RDSEED to extract miniseed files from a single SEED file. The program works, but the output is in a single miniSEED file.

Is it possible to extract separate miniseed files for each channel, similar to the output files extracted in SAC format?

Kind regards,
Matthew

Hi Matthew,

You can use the dataselect tool. From the man page (2015-02-19):

dataselect selects, sorts and prunes Mini-SEED data. Any output data will always be sorted by ascending time-series segments. Various data selection operations are possible including time criteria, the removal of duplicate data and the splicing of partially overlapping data records to form continuous time-series.

Data pruning, removal of overlap, can be performed at either the record or sample level. Pruning at the record level guarantees that records are never unpacked/repacked, but this could potentially leave small amounts of overlap in the data. Pruning at the sample level will remove any overlap and splice data to within the time-series tolerance, this requires the unpacking and repacking of data records and is done in a modification-minimizing way.
