> Classic modeling benchmarks
-----------------------------

The classic Rosetta and I-Tasser protein modeling benchmarks were
downloaded from http://fons.bakerlab.org/rosetta_decoys_62proteins.tgz
and https://zhanglab.ccmb.med.umich.edu/decoys, respectively.

Benchmark     Targets   Structures
id              [#]        [#]
----------------------------------
rosetta41        41        4599
itasser56        56       24650

The rosetta41/ directory contains well-scoring Rosetta protein decoys
(e.g. 1scj_073.pdb) and their native crystal structures (e.g.
1scj.pdb). Natives were refined in Rosetta to produce 20 relaxed
decoys (e.g. 1scj_rx_15.pdb) relieving clashes and, in some cases,
repacking rotamers. See the README in the author's downloaded file
for more information (not provided here).

The itasser56/ directory contains the decoys for the 56 non-homologous
small proteins of the Decoy Set II. This decoy set is a non-rudundant
subset of the I-TASSER decoys (Set-I). The raw decoys were first
generated by I-TASSER ab initio simulation, which were then
structurally refined by GROMACS4.0 using OPLS-AA force field with the
purpose of removing steric clashes and refining torsion angles. Each
set includes 300-500 decoys, which was used to test the atomic
potentials, including RW and RW+ potentials, see: J Zhang and Y Zhang,
A Distance-Dependent Atomic Potential Derived from Random-Walk Ideal
Chain Reference State for Protein Fold Selection and Structure
Prediction. PLoS One, vol 5, e15386 (2010).

Note that a plain-text table ("TMall" file, e.g. rosetta41_TMall.txt) with
the C-alpha RMSDs, scores (TM, MS and GDT_TS), and the energies
computed using others potentials (ICOSA, RW+, GOAP, ORDER_AVE, VoroQ,
DOSP, and CSF) can be found inside each benchmark sub-directory.
