Bio::Map::Physical(3) User Contributed Perl DocumentationBio::Map::Physical(3)NAMEBio::Map::Physical - A class for handling a Physical Map (such as FPC)
SYNOPSIS
use Bio::MapIO;
# accquire a Bio::Map::Physical using Bio::MapIO::fpc
my $mapio = Bio::MapIO->new(-format => "fpc",-file => "rice.fpc",
-readcor => 0);
my $physical = $mapio->next_map();
# get all the markers ids
foreach my $marker ( $physical->each_markerid() ) {
print "Marker $marker\n";
# acquire the marker object using Bio::Map::FPCMarker
my $markerobj = $physical->get_markerobj($marker);
# get all the clones hit by this marker
foreach my $clone ($markerobj->each_cloneid() ) {
print " +++$clone\n";
}
}
DESCRIPTION
This class is basically a continer class for a collection of Contig
maps and other physical map information.
Bio::Map::Physical has been tailored to work for FPC physical maps, but
could probably be used for others as well (with the appropriate MapIO
module).
This class also has some methods with specific functionalities:
print_gffstyle() : Generates GFF; either Contigwise[Default] or
Groupwise
print_contiglist() : Prints the list of Contigs, markers that hit the
contig, the global position and whether the marker
is a placement (<P>) or a Framework (<F>) marker.
print_markerlist() : Prints the markers list; contig and corresponding
number of clones.
matching_bands() : Given two clones [and tolerence], this method
calculates how many matching bands do they have.
coincidence_score() : Given two clones [,tolerence and gellen], this
method calculates the Sulston Coincidence score.
For faster access and better optimization, the data is stored
internally in hashes. The corresponding objects are created on request.
FEEDBACK
Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to the
Bioperl mailing list. Your participation is much appreciated.

Support
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly address
it. Please include a thorough description of the problem with code and
data examples if at all possible.
Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track of
the bugs and their resolution. Bug reports can be submitted via the

PROJECT DESCRIPTION
The project was done in Arizona Genomics Computational Laboratory
(AGCoL) at University of Arizona.
This work was funded by USDA-IFAFS grant #11180 titled "Web Resources
for the Computation and Display of Physical Mapping Data".
