Bio::MapIO::fpc - A FPC Map reader


# do not use this object directly it is accessed through the Bio::MapIO system

    use Bio::MapIO;
     -format  : specifies the format of the file format is "fpc",
     -file    : specifies the name of the .fpc file
     -readcor : boolean argument, indicating if .cor is to be read
                 or not. It looks for the .cor file in the same path
                 as .fpc file.
                 0 : doesn't read .cor file
                 1 : reads the .cor file
                 [default 0]
     -verbose : indicates the process of loading of fpc file
    my $mapio = Bio::MapIO->new(-format  => "fpc",
                               -file    => "rice.fpc",
                               -readcor => 0,
                               -verbose => 0);
    my $map = $mapio->next_map();
    foreach my $marker ( $map->each_markerid() ) {
         # loop through the markers associated with the map
         # likewise for contigs, clones, etc.


This object contains code for parsing and processing FPC files and creating Bio::Map::Physical object from it.

For faster access and better optimization, the data is stored internally in hashes. The corresponding objects are created on request.

We handle reading of the FPC ourselves, since MapIO module of Bioperl adds too much overhead.

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.                  - General discussion  - About the mailing lists


Please direct usage questions or support issues to the mailing list:

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.
