DESCRIPTION

This class describes a local mutation event using minimalistic description. It is not necessary to know anything about the original sequence. You need to give the changed sequence, the position of the mutation in the (unidentified) reference sequence, and the length of the affected subsequence in the reference sequence. If the original allele sequence is given, the objects applying the mutation into the reference sequence (e.g. Bio::LiveSeq::Mutator) might check for its validity.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

seq

 Title   : seq
 Usage   : $obj->seq();
 Function: 

            Sets and returns the mutated sequence. No checking is done
            to validate the symbols.

 Example : 
 Returns : string
 Args    : integer

seqori

 Title   : seqori
 Usage   : $obj->seqori();
 Function: 

            Sets and returns the original subsequence in the reference
            sequence. No checking is done to validate the symbols.
            Optional value.

 Example : 
 Returns : string
 Args    : string

pos

 Title   : pos
 Usage   : $obj->pos();
 Function: 

            Sets and returns the position of the first element in the
            sequence.

 Example : 
 Returns : string
 Args    : integer

len

 Title   : len
 Usage   : $obj->len();
 Function: 

            Sets and returns the len of the affected original allele
            sequence.  If value is not set, defaults to the lenght of
            the mutated sequence (seq).

 Example : 
 Returns : string
 Args    : string

label

 Title   : label
 Usage   : $obj->label();
 Function: 

            Sets and returns the label of the affected original allele
            location. Label is a stable identifier whereas location
            can be changed by mutations. Label comes from
            l<Bio::LiveSeq::Gene>.

 Example : 
 Returns : string
 Args    : string

transpos

 Title   : transpos
 Usage   : $obj->transpos();
 Function: 

            Sets and returns the transcript position of the mutation.
            Set when associated with a reference sequence. Value
            depends on reference molecule and the co-ordinate system
            used.

 Example : 
 Returns : string
 Args    : integer

issue

 Title   : issue
 Usage   : $obj->issue();
 Function: 

            Sets and returns the position of the mutation in an array
            of mutations to be issued. Set after the validity of the
            mutation has been confirmed.

 Example : 
 Returns : string
 Args    : integer

prelabel

 Title   : prelabel
 Usage   : $obj->prelabel();
 Function: 

            Sets and returns the prelabel of the affected original allele
            location. Prelabel is a stable identifier whereas location
            can be changed by mutations. Prelabel comes from
            l<Bio::LiveSeq::Gene>.

 Example : 
 Returns : string
 Args    : string

postlabel

 Title   : postlabel
 Usage   : $obj->postlabel();
 Function: 

            Sets and returns the postlabel of the affected original allele
            location. Postlabel is a stable identifier whereas location
            can be changed by mutations. Postlabel comes from
            l<Bio::LiveSeq::Gene>.

 Example : 
 Returns : string
 Args    : string

lastlabel

 Title   : lastlabel
 Usage   : $obj->lastlabel();
 Function: 

            Sets and returns the lastlabel of the affected original allele
            location. Lastlabel is a stable identifier whereas location
            can be changed by mutations. Lastlabel comes from
            l<Bio::LiveSeq::Gene>.

 Example : 
 Returns : string
 Args    : string

cpanm Bio::Seq

perl -MCPAN -e shell
