read from Mini-SEED
command: READS <path> <time> <seclength> <stations> <comps> <chan>
Reads traces from Mini-SEED files via a special directory file (sfd-file). The traces read are added to the display list.
parameters
- <path> parameter type: string
Specifies the path to the sfd-file. Usually this is the name of an environment variable which points to this path followed by a colon (like "sfd:").
- <time> parameter type: time
Absolute time to be read from file (string containing no blanks like "25,2,96,3,27" or "25-feb-96_3:27"). [At SZGRF only: <time> == "ONLINE" reads online data.]
- <seclength> parameter type: real
Time window in seconds read in.
- <stations> parameter type: string
Comma separated list of stations (no blanks !) or abbreviations "grf" (all GRF stations) or "all" (all GRSN stations).
- <comps> parameter type: string
List of components like "zne" or "z".
- <chan> parameter type: string
2-character channel specifier (SEED naming conventions) like "bh", "lh" and others.
qualifiers
- /close
Does not read but closes all previously opened SEED files.
- /force
Creates zero traces if specified time and channel is not available for a station.
- /sfd=<sfdfile>
Name of sfd-file used in directory <path>. Necessary only if the name is different from "sfdfile.sfd".
- /[no]swap Requests/Prevents? byte-swapping of data when reading SEED data. Default is /SWAP.
- /[no]invhdr Requests/Prevents? byte-swapping of header information when reading SEED data. Default is /NOINVHDR.
examples
- reads SFD: 23-feb-96_8:23 600 GRF ZNE BH
- reads 10min of GRF data from sfd-path SFD
- reads %HERE 23,2,96,8,23 600 GRA1,GRB1,GRC1 Z BH
- reads 10 minutes of 3 stations GRA1, GRB1, GRC1 from sfd-file which is on current working directory.
