Exploratory Data Analysis

(1) MSA Profile frequencies used for histograms and Hinton plots
    --> check msa profile amino acid ordering
    --> missing sequence profile 3emn.X --> possibly removed as it was
		Eukaryote?

(2) Check PDB entry updates for RSAS as chains from Boctopus data do not
	match PDB entries.
	--> 1e54.E, 3a25.G, 3prn.C, 2por.C 

(3) Hydrophobic Moment

Todo:-
Other feature indicators and encodings. Also use PCA to reduce
dimensions of features.
Obtain grammar for TMBs from Fariselli.
Decide on number of mixtures for hidden states (clustering analysis?)
