NAME ^

Bio::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.
