Revision 1.1 - (download) (as text) (annotate)
Wed Jun 21 07:52:52 2006 UTC (13 years, 11 months ago) by parrello
Branch: MAIN
Added to allow locations to be appended to streams with feature data.

#!/usr/bin/perl -w

=head1 Feature Location Computer

This script adds feature locations to a data mining stream. The locations
are formatted as Sprout locations, consisting of the contig ID, the start
position, the direction, and the length. If a feature has multiple
locations, each one will produce a separate output line.

The currently-supported command-line options are as follows.

=over 4

=item keyColumn

Name or number of the column containing the feature ID.

=item user

Name suffix to be used for log files. If omitted, the PID is used.

=item trace

Numeric trace level. A higher trace level causes more messages to appear. The
default trace level is 2. Tracing will be directly to the standard output
as well as to a C<trace>I<User>C<.log> file in the FIG temporary directory,
where I<User> is the value of the B<user> option above.

=item sql

If specified, turns on tracing of SQL activity.

=item background

Save the standard and error output to files. The files will be created
in the FIG temporary directory and will be named C<err>I<User>C<.log> and
C<out>I<User>C<.log>, respectively, where I<User> is the value of the
B<user> option above.

=item h

Display this command's parameters and options.
