Parameter manifold searching
--> Multiple bash scripts for different cross-validation sets to
	increase parallelism of processing.
--> Be sure to check input/output file names incase of file_io errors.
--> Fixed sys.exit call in forward_mat function call due to scale list
	having zero value entries. 

(1) Test different input representations
	--> msa profile (created)
	--> hydrophobic moment profile (created)
	--> msa + hyydrophobic moment profiles (created)
	--> pca of msa profile (need to create)
	--> single seq + msa profile (created)

(2) PSICOV --> contact map estimation
	--> look for significant local correlation as most people only search
		for non-local correlation for beta-strands
	--> data stored on server at /gluster/data/tmb_maps.tgz
	
(3) Non-negative matrix factorisation

(4) Different grammars, mixtures, and window sizes
	--> tied at mixture level not state level
	--> different mixture numbers (1,3,and 4)
	--> window sizes (5,7,11,15,19,21,29,31)
