Module: SeqFeature Bio/SeqFeature.py

Represent a Sequence Feature holding info about a part of a sequence.

This is heavily modeled after the Biocorba SeqFeature objects, and may be pretty biased towards GenBank stuff since I'm writing it for the GenBank parser output...

What's here:

Base class to hold a Feature. ---------------------------- classes: o SeqFeature

Hold information about a Reference. ----------------------------------

This is an attempt to create a General class to hold Reference type information.

classes: o Reference

Specify locations of a feature on a Sequence. ---------------------------------------------

This aims to handle, in Ewan's words, the dreaded fuzziness issue in much the same way as Biocorba. This has the advantages of allowing us to handle fuzzy stuff in case anyone needs it, and also be compatible with Biocorba.

classes: o FeatureLocation - Specify the start and end location of a feature.

  • ExactPosition - Specify the position as being exact. o WithinPosition - Specify a position occuring within some range. o BetweenPosition - Specify a position occuring between a range. o BeforePosition - Specify the position as being found before some base. o AfterPosition - Specify the position as being found after some base.

Classes   
AbstractPosition

Abstract base class representing a position.

AfterPosition

Specify a position where the actual location is found after it.

BeforePosition

Specify a position where the actual location occurs before it.

BetweenPosition

Specify the position of a boundary between two coordinates.

ExactPosition

Specify the specific position of a boundary.

FeatureLocation

Specify the location of a feature along a sequence.

OneOfPosition

Specify a position where the location can be multiple positions.

PositionGap

Simple class to hold information about a gap between positions.

Reference

Represent a Generic Reference object.

SeqFeature

Represent a Sequence Feature on an object.

WithinPosition

Specify the position of a boundary within some coordinates.
