       mseed2sac - miniSEED to SAC converter


       mseed2sac [options] file1 [file2 file3 ...]


       mseed2sac  converts  miniSEED  waveform  data  to  SAC format.  The output SAC file can be
       either ASCII or binary (either byte-order), the default is binary with the same byte-order
       as  the  host  computer.   By  default  all  aspects  of the input files are automatically

       If an input file name is prefixed with an '@' character the file is assumed to  contain  a
       list of input data files, see INPUT LIST FILES below.

       A  separate  output  file  is  written  for each continuous time-series in the input data.
       Output file names are of the form:


       For example:

       Files that would have the same file name due to having the same start time  will  be  kept
       separate  by  adding a digit to file name.  The -O argument changes this behavior to allow
       overwriting of existing file names.

       If the input file name is "-" input miniSEED records will be read from standard input.

       The SAC header variable KHOLE is used synonymously  with  the  SEED  location  code.   Any
       location  codes  found  in  the  input  miniSEED  or  metadata file are put into the KHOLE


       -V     Print program version and exit.

       -h     Print program usage and exit.

       -H     Print extended program usage with all options and exit.

       -v     Be more verbose.  This flag can be used multiple times ("-v -v" or "-vv") for  more

       -O     Overwrite an existing files instead of generating new file names.

       -k lat/lon
              Specify  station  coordinates  to  put  into  the output SAC file(s).  The argument
              format is "Latitude/Longitude" e.g. "47.66/-122.31".   Coordinates  specified  with
              this option override any coordinates found in the metadata file.

       -m metafile
              Specify  a  file  containing  metadata  such  as  coordinates, elevation, component
              orientation, scaling factor,  etc.   For  each  time-series  written  any  matching
              metadata will be added to the SAC header.  See METADATA FILES below.

       -M metaline
              Specify a "line" of metadata in the same format as expected for the METADATA FILES.
              This option may be specified multiple times.

       -msi   Convert any component inclination values in a metadata file from SEED (dip) to  SAC
              convention, this is a simple matter of adding 90 degrees.

       -E event
              Specify event parameters to add to the SAC file in the following format:


              For example:

              The parameters later in the string are optional.

       -l selectfile
              Limit  to  miniSEED  records  that  match  a  selection in the specified file.  The
              selection file  contains  parameters  to  match  the  network,  station,  location,
              channel,  quality and time range for input records.  This option only trims data to
              SEED record  granularity,  not  sample  granularity.   For  more  details  see  the
              SELECTION FILE section below.

       -f format
              The  default  output  format  is  binary  SAC  with the same byte order as the host
              computer.  This option forces the format for every output file:

              1 : Alphanumeric SAC format
              2 : Binary SAC format, host byte order (default)
              3 : Binary SAC format, little-endian
              4 : Binary SAC format, big-endian

       -N netcode
              Specify the network code to use, overriding any network code in the input miniSEED.

       -S station
              Specify the station code to use, overriding any station code in the input miniSEED.

       -L location
              Specify the location code to  use,  overriding  any  location  code  in  the  input

       -C channel
              Specify the channel code to use, overriding any channel code in the input miniSEED.

       -r bytes
              Specify the miniSEED record length in bytes, by default this is autodetected.

       -i     Process  each input file individually.  By default all input files are read and all
              data is buffered in memory before SAC files are written.  This  allows  time-series
              spanning  mutilple  input files to be merged and written in a single SAC file.  The
              intention is to use this option when processing large amounts of data in  order  to
              keep memory usage within reasonable limits.

       -ic    Process  each  input  channel  individually.  Similar to the -i option, except this
              instructs the program to create write SAC files for each channel  (determined  when
              the  input  channel  changes).   Data  should  be  well ordered by channel for best
              results.  This option can be used to reduce memory usage for very large input files
              containing many channels.

       -dr    Use  the  sampling  rate  derived  from  the  start and end times and the number of
              samples instead of the rate specified in the input data.  This is useful  when  the
              sample rate in the input data does not have enough resolution to represent the true

       -z zipfile
              Create a ZIP archive containing all SAC files instead of writing individual  files.
              Each  file  is compressed with the deflate method.  Specify "-" (dash) to write ZIP
              archive to stdout.

       -z0 zipfile
              Same as "-z" except do not compress the SAC files.  Specify "-" (dash) to write ZIP
              archive to stdout.


       A  metadata file contains a list of station parameters, some of which can be stored in SAC
       but not in miniSEED.  Each line in a metadata file should be a list of parameters  in  the
       order shown below.  Each parameter should be separated with a comma or a vertical bar (|).
       DIP CONVENTION: When comma separators are used the dip field (CMPINC) is assumed to be  in
       the  SAC convention (degrees down from vertical up/outward), if vertical bars are used the
       dip field is assumed to be in the SEED  convention  (degrees  down  from  horizontal)  and
       converted to SAC convention.

       Metdata fields:
       Network (KNETWK)
       Station (KSTNM)
       Location (KHOLE)
       Channel (KCMPNM)
       Latitude (STLA)
       Longitude (STLO)
       Elevation (STEL), in meters [not currently used by SAC]
       Depth (STDP), in meters [not currently used by SAC]
       Component Azimuth (CMPAZ), degrees clockwise from north
       Component Incident Angle (CMPINC), degrees from vertical
       Instrument Name (KINST), up to 8 characters
       Scale Factor (SCALE)
       Scale Frequency, unused
       Scale Units, unused
       Sampling rate, unused
       Start time, used for matching
       End time, used for matching

       As a special case '--' can be used to match an empty location code.

       For  each  time-series  written,  metadata  from  the first line with matching source name
       parameters (network, station, location and channel) and time window (if specified) will be
       inserted  into  the  SAC  header.   All  parameters are optional except for the first four
       fields specifying the source name parameters.

       Simple wildcarding: for the source name parameters that will be matched a '*' character in
       a  field  will match anything.  The BHZ metadata lines above, for example, can be (almost)
       summarized as:

       IU,ANMO,*,BHZ,34.9459,-106.4571,1671,145,0,0,Geotech KS-54000,3456610000,0.02,M/S,20,2008-06-30T20:00:00,2599-12-31T23:59:59


       A selection file is used to match input data records based on network,  station,  location
       and  channel  information.   Optionally a quality and time range may also be specified for
       more refined selection.  The non-time fields may use the '*' wildcard  to  match  multiple
       characters  and  the  '?' wildcard to match single characters.  Character sets may also be
       used, for example '[ENZ]' will match either E, N or Z.  The '#'  character  indicates  the
       remaining portion of the line will be ignored.

       Example selection file entires (the first four fields are required)
       #net sta  loc  chan  qual  start             end
       IU   ANMO *    BH?
       II   *    *    *     Q

       If  an  input file is prefixed with an '@' character the file is assumed to contain a list
       of file for input.  Multiple list files can be combined with multiple input files  on  the
       command line.  The last, space separated field on each line is assumed to be the file name
       to be read.
