-score => { no_score => 334 }
);
DESCRIPTION¶
Bio::SeqFeature::Computation extends the Generic seqfeature object with a set of
computation related fields and a more flexible set of storing more types of
score and subseqfeatures. It is compatible with the Generic SeqFeature object.
The new way of storing score values is similar to the tag structure in the
Generic object. For storing sets of subseqfeatures the array containg the
subseqfeatures is now a hash which contains arrays of seqfeatures Both the
score and subSeqfeature methods can be called in exactly the same way, the
value's will be stored as a 'default' score or subseqfeature.

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.

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.

DEVELOPERS¶
This class has been written with an eye out of inheritance. The fields the
actual object hash are:
_gsf_sub_hash = reference to a hash containing sets of sub arrays
_gsf_score_hash= reference to a hash for the score values
APPENDIX¶
The rest of the documentation details each of the object methods. Internal
methods are usually preceded with a _
has_score¶
Title : has_score
Usage : $value = $self->has_score('some_score')
Function: Tests wether a feature contains a score
Returns : TRUE if the SeqFeature has the score,
and FALSE otherwise.
Args : The name of a score
add_score_value¶
Title : add_score_value
Usage : $self->add_score_value('P_value',224);
Returns : TRUE on success
Args : score (string) and value (any scalar)
score¶
Title : score
Usage : $value = $comp_obj->score()
$comp_obj->score($value)
Function: Returns the 'default' score or sets the 'default' score
This method exist for compatibility options
It would equal ($comp_obj->each_score_value('default'))[0];
Returns : A value
Args : (optional) a new value for the 'default' score
each_score_value¶
Title : each_score_value
Usage : @values = $gsf->each_score_value('note');

under a particular score.
Returns : A list of scalars
Args : The name of the score
all_scores¶
Title : all_scores
Usage : @scores = $feat->all_scores()
Function: Get a list of all the scores in a feature
Returns : An array of score names
Args : none
remove_score¶
Title : remove_score
Usage : $feat->remove_score('some_score')
Function: removes a score from this feature
Returns : nothing
Args : score (string)

as to whether it lies inside the parent, and throw
an exception if not.
If EXPAND is used, the parents start/end/strand will
be adjusted so that it grows to accommodate the new
subFeature,
optionally a seqfeature type can be defined.

(if you want to remove a more specific subset, take an array of them
all, flush them, and add back only the guys you want)
Example :
Returns : none
Args : none
