Bio::Map::Physical - A class for handling a Physical Map (such as FPC)
use Bio::MapIO;
# acquire 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";
}
}
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.
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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
These methods let you get and set the member variables
Title : version
Usage : my $version = $map->version();
Function: Get/set the version of the program used to
generate this map
Returns : scalar representing the version
Args : none to get, OR string to set

Title : group_type
Usage : $map->group_type($grptype);
my $grptype = $map->group_type();

Title : group_abbr
Usage : $map->group_abbr($grpabbr);
my $grpabbr = $map->group_abbr();
Function: get/set the group abbrev of this map
Returns : string representing the group abbrev
Args : none to get, OR string to set
Title : core_exists Usage : my $core_exists = $map->core_exists(); Function: Get/set if the FPC file is accompanied by COR file Returns : boolean Args : none to get, OR 1|0 to set

Function: returns an object of the contig given in the argument
Returns : object of the contig
Args : scalar representing the contig number
Title : matching_bands
Usage : $self->matching_bands('cloneA','cloneB',[$tol]);
Function: given two clones [and tolerence], this method calculates how many
matching bands do they have.
(this method is ported directly from FPC)
Returns : scalar representing the number of matching bands

[Default tol=7 gellen=3300.0]
Title : print_contiglist
Usage : $map->print_contiglist([showall]); #[Default 0]
Function: 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.
Returns : none
Args : [showall] [Default 0], 1 includes all the discrepant markers
Title : print_markerlist
Usage : $map->print_markerlist();
Function : prints the marker list; contig and corresponding number of
clones for each marker.
Returns : none

Title : _set<Type>Ref
Usage : These are used for initializing the reference of the hash in
Bio::MapIO (fpc.pm) to the corresponding hash in Bio::Map
