α-helices in all-α proteins

Dataset containing physical-chemical and strucutural descriptors for α-helices and its flanking regions.
Only α-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.
