Exclusive α-helices in all-α proteins

Dataset containing physical-chemical and strucutural descriptors for exclusive α-helices (only a single helical structure segment is present in the protein's whole structure) and its flanking regions.Only alpha helices from all-α proteins are eligible for this dataset.Data is organized into sections. Each section begins with the following header: length, pdb_name, chain_id, flag, position, [parameter].length is the number of amino acid residues comprising the α-helix.flag indicates the amino acid residue underlying region, namely: flanking region before the α-helix (); α-helix (=); flanking region after the α-helix (>).[parameter]: paramater's value for the given amino acid residue. All parameters are extracted from the STING Database.Example:Solvent-accessible surface area for all amino acid residues forming an α-helix of length 6length, pdb_name, chain_id, flag, position, Accessible_Surface_in_Isolation6,1not,A,=,1,136.5856,1not,A,=,2,106.0686,1not,A,=,3,11.3226,1not,A,=,4,49.5176,1not,A,=,5,227.676,1not,A,=,6,110.9
