Visualize significant conserved amino acid sequence pattern in groups
based on probability theory
Description
We implement iceLogo by R to visualize significant conserved amino acid sequence pattern
based on probability theory. Compare to iceLogo, dagLogo can also visualize significant
sequence patterns by clustering the peptides by groups such as charge, chemistry, hydrophobicity
and etc.

DAG: Differential Amino acid Group
There are several differences between dagLogo from iceLogo:
1. The sequence patterns can be grouped by charge, chemistry, hydrophobicity and etc.
2. dagLogo accepts different length of aligned amino acid sequences.
3. Except Random, regional (called restricted in dagLogo) and terminal
(called anchored) background model, the background sequence could be set to
other regions of the genes in inputs and complementary set of the proteome.
