Bio.Wise contains modules for running and processing the output of some of the models in the Wise2 package by Ewan Birney available from: ftp://ftp.ebi.ac.uk/pub/software/unix/wise2/ http://www.ebi.ac.uk/Wise2/

Bio.Wise.psw is for protein Smith-Waterman alignments Bio.Wise.dnal is for Smith-Waterman DNA alignments

exception Bio.Wise.psw.AlignmentColumnFullException

Bases: Exception

Manage exception in the alignment output.

class Bio.Wise.psw.Alignment(iterable=(), /)

Bases: list

Define a container for all alignment Columns, output from running psw.

append(column_unit)

Add an alignment Column to Alignment.

class Bio.Wise.psw.AlignmentColumn(column_unit)

Bases: list

Define a container for the units that made the Column.

__init__(column_unit)

Initialize the class.

__repr__()

Represent the AlignmentColumn object as a string for debugging.

append(column_unit)

Add a unit to the Column.

class Bio.Wise.psw.ColumnUnit(unit, column, kind)

Bases: object

Define a container for the details of each sequence alignment.

__init__(unit, column, kind)

Initialize the class.

__repr__()

Represent the ColumnUnit object as a string for debugging.

Bio.Wise.psw.parse_line(line)

Parse a line from psw.

>>> print(parse_line("Column 0:"))
None
>>> parse_line("Unit  0- [  -1-   0] [SEQUENCE]")
ColumnUnit(unit=0, column=0, kind='SEQUENCE')
>>> parse_line("Unit  1- [  85-  86] [SEQUENCE]")
ColumnUnit(unit=1, column=86, kind='SEQUENCE')

Bio.Wise.psw.parse(iterable)

Parse a file.

format

Column 0: Unit 0- [ -1- 0] [SEQUENCE] Unit 1- [ 85- 86] [SEQUENCE]

means that seq1[0] == seq2[86] (0-based)

Bio.Wise.psw.align(pair, scores=None, gap_start=None, gap_extension=None, *args, **keywds)

Align a pair of DNA files using Wise2 psw.

Bio.Wise.psw.main()

Command line implementation.
