Bio::Location::Simple - Implementation of a Simple Location on a Sequence
use Bio::Location::Simple;
my $location = Bio::Location::Simple->new(
-start => 1,
-end => 100,
-strand => 1,
);
if( $location->strand == -1 ) {
printf "complement(%d..%d)\n", $location->start, $location->end;
} else {
printf "%d..%d\n", $location->start, $location->end;
}
This is an implementation of Bio::LocationI to manage exact location information on a Sequence: '22' or '12..15' or '16^17'.
You can test the type of the location using length() function () or directly location_type() which can one of two values: 'EXACT' or 'IN-BETWEEN'.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.

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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : start
Usage : $start = $loc->start();
Function: get/set the start of this range
Returns : the start of this range
Args : optionally allows the start to be set
using $loc->start($start)
Title : end
Usage : $end = $loc->end();
Function: get/set the end of this range
Returns : the end of this range
Args : optionally allows the end to be set
: using $loc->end($start)
Note : If start is set but end is undefined, this now assumes that start
is the same as end but throws a warning (i.e. it assumes this is
a possible error). If start is undefined, this now throws an
exception.
Title : strand
Usage : $strand = $loc->strand();
Function: get/set the strand of this range
Returns : the strandedness (-1, 0, +1)
Args : optionally allows the strand to be set
: using $loc->strand($strand)
Title : length Usage : $len = $loc->length(); Function: get the length in the coordinate space this location spans Example : Returns : an integer Args : none
Title : min_start Usage : my $minstart = $location->min_start(); Function: Get minimum starting location of feature startpoint Returns : integer or undef if no minimum starting point. Args : none
Title : max_start
Usage : my $maxstart = $location->max_start();
Function: Get maximum starting location of feature startpoint.
In this implementation this is exactly the same as min_start().
Returns : integer or undef if no maximum starting point.
Args : none
Title : start_pos_type
Usage : my $start_pos_type = $location->start_pos_type();
Function: Get start position type (ie <,>, ^).
Returns : type of position coded as text
('BEFORE', 'AFTER', 'EXACT','WITHIN', 'BETWEEN')
Args : none
Title : min_end Usage : my $minend = $location->min_end(); Function: Get minimum ending location of feature endpoint Returns : integer or undef if no minimum ending point. Args : none
Title : max_end
Usage : my $maxend = $location->max_end();
Function: Get maximum ending location of feature endpoint
In this implementation this is exactly the same as min_end().
Returns : integer or undef if no maximum ending point.
Args : none
Title : end_pos_type
Usage : my $end_pos_type = $location->end_pos_type();
Function: Get end position type (ie <,>, ^)
Returns : type of position coded as text
('BEFORE', 'AFTER', 'EXACT','WITHIN', 'BETWEEN')
Args : none
Title : location_type
Usage : my $location_type = $location->location_type();
Function: Get location type encoded as text
Returns : string ('EXACT' or 'IN-BETWEEN')
Args : 'EXACT' or '..' or 'IN-BETWEEN' or '^'
Title : is_remote
Usage : $is_remote_loc = $loc->is_remote()
Function: Whether or not a location is a remote location.
A location is said to be remote if it is on a different
'object' than the object which 'has' this
location. Typically, features on a sequence will sometimes
have a remote location, which means that the location of
the feature is on a different sequence than the one that is
attached to the feature. In such a case, $loc->seq_id will
be different from $feat->seq_id (usually they will be the
same).
While this may sound weird, it reflects the location of the
kind of AL445212.9:83662..166657 which can be found in GenBank/EMBL
feature tables.
Example :
Returns : TRUE if the location is a remote location, and FALSE otherwise
Args : Value to set to
Title : to_FTstring Usage : my $locstr = $location->to_FTstring() Function: returns the FeatureTable string of this location Returns : string Args : none
Title : valid_Location
Usage : if ($location->valid_location) {...};
Function: boolean method to determine whether location is considered valid
(has minimum requirements for Simple implementation)
Returns : Boolean value: true if location is valid, false otherwise
Args : none
