Sequence Logos are a common technique for visualizing the conservation of positions within a multiple sequence alignment. The technique creates an image where the height of the letter represents its sequence conservation.
The Matlab bioinformatics toolbox has a function which performs this analysis and visualization. However, the figure it generates is a specialized java object and cannot be modified in any meaningful way.
This wrapper re-creates the image in a way that's more friendly for modifications of things like tick-labels, titles, letter colors, embedding in subplots or GUI's etc.
This function uses the image-processing toolbox to generate an "image" which has the letters transformed to the "proper" size.
This function was based off of suggestions from this StackOverflow post:
