1.drugname - Optional. The name to be displayed on screens.
	
	2.lignum - Ligand 3-letter code, multiple ligands are separated by commas.
	
	3.subs - Optional. Lists of comma-separated atoms to be selected for each ligand respectively, separated by |.
	Empty string: Default selection (Heteroatom), e.g., subs=N3,N8||N1,O5
	_: Select none, e.g., subs=N3,N8|_|N1,O5
	If "subs" has more than "lignum", extra atom lists will be ignored, e.g., lignum=STI,STU&subs=N3,N8|N3,O6|N1,O5.
	If "subs" has less than "lignum", last atom list will be applied to all the rest of ligands, e.g., lignum=STI,STU,UCN&subs=N3,N8|N3,O6.
	

	1.ligand - Ligand 3-letter code, multiple ligands are separated by commas.
	
	2.v - Optional. Version of Binding-Distance Correlation(Default Value: 1).
	Version 1: All PDB
	Version 2: Filter PDB
	Version 3: Filter by Uniprot
	Version 4: Only Ki Kd 
	
	3.squared - Optional. Add the squared term in equation.
