# Bio::Tools::Run::Seg(3pm)

Object for identifying low complexity regions in a given protein seequence.

## NAME

Bio::Tools::Run::Seg - Object for identifying low complexity\
   regions in a given protein seequence.

## SYNOPSIS

```
  # Build a Seg factory
  # $paramfile is the full path to the seg binary file
  my @params = ('PROGRAM',$paramfile);
  my $factory = Bio::Tools::Run::Seg->new($param);
  # Pass the factory a Bio::Seq object
  # @feats is an array of Bio::SeqFeature::Generic objects
  my @feats = $factory->run($seq);
```

## DESCRIPTION

Seg is a program which identifies low complexity regions in proteins. It was developed by Wootton and Federhen at NCBI.

## 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 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.
