All designing sequences and their ground states for the HP model for 4 ≤ N ≤ 30 in a plain text format:
HP_designing.tar.gz
Each HPnXX.txt file contains all designable conformations and designing sequence for N = 'XX'. Each line either contains a conformation described by N-1 of the letters 'UDRL', or a sequence that designs the preceeding conformations. Lines with sequences begin with two spaces, followed by a sequence specified by N letters ('H' or 'P'), followed by a single space and finally the number of HH contacts (i.e. minus the ground state energy) as a decimal number. All conformations start with U and the first turn is to the right.
Energy histograms for all designing sequences for 4 ≤ N ≤ 22 and N = 27. For other N ≤ 30, the files only include sequences in the neutral net of conformations with designability above the cutoff determined by uniqueness of the prototype sequence.
energyhistograms.tar.gz
Reversing a sequence does not alter the energy histogram, so for non-palindrome sequences only one of the directions is listed.
The C++ programs used to generate the files are available upon request. As of 2020, they are still maintained.
