# Bio::SeqEvolution::EvolutionI(3pm)

the interface for evolving sequences

## NAME

Bio::SeqEvolution::EvolutionI - the interface for evolving sequences

## SYNOPSIS

```
    # not an instantiable class
```

## DESCRIPTION

This is the interface that all classes that mutate sequence objects in constant fashion must implement. A good example is Bio::SeqEvolution::DNAPoint.

## 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.

```
  bioperl-l@bioperl.org                  - General discussion
  http://bioperl.org/wiki/Mailing_lists  - About the mailing lists
```

### 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.

### Reporting Bugs

## APPENDIX

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

### annotation

```
 Title   : annotation
 Usage   : $obj->annotation($newval)
 Function: Get the annotation collection for this annotatable object.
 Example :
 Returns : a Bio::AnnotationCollectionI implementing object, or undef
 Args    : on set, new value (a Bio::AnnotationCollectionI
           implementing object, optional) (an implementation may not
           support changing the annotation collection)
```

See Bio::AnnotationCollectionI

### seq

```
 Title   : seq
 Usage   : $obj->seq($newval)
 Function: Set the sequence object for the original sequence
 Returns : The sequence object
 Args    : newvalue (optional)
```

Setting this will reset mutation and generated mutation counters.

### next\_seq

```
  Title   : next_seq
  Usage   : $obj->next_seq
  Function: Evolve the reference sequence to desired level
  Returns : A new sequence object mutated from the reference sequence
  Args    : -
```

### mutate

```
  Title   : mutate
  Usage   : $obj->mutate
  Function: mutate the sequence at the given location according to the model
  Returns : true
  Args    : integer, start location of the mutation, required argument
```

Called from *next\_seq()*.
