X_SETUP(1)                   Generic Mapping Tools                  X_SETUP(1)

NAME
       x_setup - Determine Pairs of Legs that need Cross-Over Checking

SYNOPSIS
       x_setup [ -Llegfile ] [ -Rwest/east/south/north ]

DESCRIPTION
       x_setup scans the gmtindex.b file that contains information on which
       legs occupy each 1 by 1 degree bin and reports all the pairs of legs
       that may overlap. Each pair is only reported once, even if the two legs
       involved are found in other bins also.

       -L     Only report pairs where at least one of the legs are present in
              the legfile.

       -R     The region of interest.  [Default is world]

BEWARE
       The -L option is useful when one wants to check out a handful of new
       cruises. Obviously we only need to compute COEs for the pairs that
       involve one or two of the new cruises, since all the other combinations
       have already been done.
