Class Motif

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__

(inherited documentation)

return the length of a motif

Please use this method (i.e. invoke len(m)) instead of referring to m.length directly.

string representation of a motif.
        

Overrides: object.__str__

Returns a string representation of the Motif in a given format

Currently supported fromats:
 - pfm : JASPAR Position Frequency Matrix
 - transfac : TRANSFAC like files

uses the Berkeley weblogo service to download and save a weblogo of
itself

requires an internet connection.
The parameters from **kwds are passed directly to the weblogo server.

Currently, this method uses WebLogo version 3.3.
These are the arguments and their default values passed to
WebLogo 3.3; see their website at http://weblogo.threeplusone.com
