biotite#

This is the top-level package of Biotite. Although it does not provide useful functionality for most users, it does provide utilities and base classes used by a lot of Biotite’s modules.

File classes#

File

Base class for all file classes.

TextFile

Base class for all line based text files.

Visualization utilities#

plot_scaled_text

Create a matplotlib.textpath.TextPath, whose text size is given in coordinates instead of font size.

AdaptiveFancyArrow

A FancyArrow with fixed head shape.

Miscellaneous#

Copyable

Base class for all objects, that should be copyable.

DeserializationError

InvalidFileError

Indicates that the file is not suitable for the requested action, either because the file does not contain the required data or because the file is malformed.

SerializationError

set_font_size_in_coord

Specifiy the font size of an existing Text object in coordinates of the object's reference coordiante system.
