x2sys_put - Update x2sys track data bases
SYNOPSIS
x2sys_put [ info.tbf ] -TTAG [ -D ] [ -F ] [ -V ]
DESCRIPTION
x2sys_put accepts a track bin-index file created by x2sys_binlist and adds this information about the data tracks to the relevant data
base. You may chose to overwrite existing data with new information for older tracks (-F) and even completely remove information for cer-
tain tracks (-D). The x2sys TAG must match the tag encoded in the info.tbf file. To inquire about tracks in the data base, use x2sys_get.
-T Specify the x2sys TAG which tracks the attributes of this data type.
OPTIONS
No space between the option flag and the associated arguments.
info.tbf
Name of a single track bin file. If not given, stdin will be read.
-D Delete all tracks found in the track bin file [Default will try to add them as new track entries].
-F Replace any existing database information for these tracks with the new information in the track bin file [Default refuses to
process tracks already in the database].
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To add the information stored in the track bin-index file latest.tbf to the track data bases associated with the tag MGD77, and replace any
exiting information for these tracks, try
x2sys_put latest.tbf -F -V -TMGD77
X2SYS DATABASES
The x2sys_put utility adds new information to the x2sys data bases. These consists of two files: The first file contains a listing of all
the tracks that have been added to the system; it is named TAG_tracks.d and is in ASCII format. The second file is named TAG_index.b and
is in native binary format. It contains information on which tracks cross each of the bins, and what data sets were observed while cross-
ing the bin. The bins are defined by the -R and -I options passed to x2sys_init when the TAG was first initiated. Both data base files
are stored in the $X2SYS_HOME/TAG directory. Do not attempt to edit these files by hand.

x2sys_get - Get track listing from the x2sys track index databases
SYNOPSIS
BD(x2sys_get) -TIT(TAG) [ -C ] [ -D ] [ -E ] [ -FIT(flags) ] [ -L[IT(list)] ] [ -NIT(flags) ] [ -Qe|BD(i) ] [ -Rwest/east/south/north[r] ]
[ -V ] ]
DESCRIPTION
BD(x2sys_get) will return the names of the track data files in the x2sys data base for this TAG that match the given requirements. You may
choose a specific region and optionally ask only for tracks that meet certain data criteria. Finally, you may select an option to list all
possible pairs that might generate crossovers.
-T Specify the x2sys TAG which tracks the attributes of this data type.
OPTIONS
No space between the option flag and the associated arguments.
-C Instead of reporting the track names, just output the coordinates of the center of each bin that has at least one track with the
specified data.
-D Only report the track names [Default adds the availability of data for each field].
-E Append the file extension to all reported tracks [no extension].
-F Give a comma-separated list of column names (as described in the definition file) that should all be present within the selected
region. [Default selects all data columns]. A track will be included in the returned list if at least one bin reports that the
track has all of the listed columns.
-L Crossover mode. Return a list of track pairs that should be checked for possible crossovers. The list is determined from the bin-
index data base on the assumption that tracks occupying the same bin are very likely to intersect. By default we return all possi-
ble pairs in the data base. Append the name of a file with a list of tracks if you want to limit the output to those pairs that
involve at least one of the track names in your list. The output is suitable for the -K option in x2sys_cross.
-N Give a comma-separated list of column names (as described in the definition file) that all must be absent. A track will be excluded
from the returned list if at least one bin reports that the track some all of the listed columns.
-Q Append e for external COEs only, and i for internal COEs only [Default is all COEs]. This applies to the crossover setup only and
requires -L.
-R west, east, south, and north specify the Region of interest, and you may specify them in decimal degrees or in
[+-]dd:mm[:ss.xxx][W|E|S|N] format. Append r if lower left and upper right map coordinates are given instead of w/e/s/n. The two
shorthands -Rg and -Rd stand for global domain (0/360 and -180/+180 in longitude respectively, with -90/+90 in latitude). Alterna-
tively, specify the name of an existing grid file and the -R settings (and grid spacing, if applicable) are copied from the grid.
For Cartesian data just give xmin/xmax/ymin/ymax. This option limits the tracks to those that fall at least partly inside the spec-
ified domain.
-V Selects verbose mode, which will send progress reports to stderr [Default runs "silently"].
EXAMPLES
To find all the tracks associated with the tag MGD77, restricted to occupy a certain region in the south Pacific, and have at least free
air anomalies and bathymetry, try
BD(x2sys_get) -V -TMGD77 -R180/240/-60/-30 -Ffaa,depth
To find all the tracks associated with the tag MGD77 that have depth but not twt, try
BD(x2sys_get) -V -TMGD77 -Fdepth -Ntwt
To find all the pairs associated with the tag MGD77 that might intersect each other, but only those pairs which involves tracks in your
list new.lis, try
BD(x2sys_get) -V -TMGD77 -Lnew.lis > xpairs.lis
NOTE
The tracks that are returned all have the requested data (-F) within the specified region (-R). Furthermore, the columns of Y and N for
other data types also reflect the content of the track portion within the selected region.
