======================================================
6 structural lignment benchmarks used in this study
======================================================

1. HOMSTRAD (from https://mizuguchilab.org/homstrad)
2. Mattbench (from http://bcb.cs.tufts.edu/mattbench/Mattbench.html)
------------------------------------------------------
3. SABMARK-TWI (twilight zone) 
4. SABMARK-SUP (superfamily)
------------ (SABMARK from http://bioinformatics.vub.ac.be/databases/databases.html)
5. SCOP1 (randomly sampled SCOP pairs aligned using DALI (DaliLite.v5) at http://ekhidna2.biocenter.helsinki.fi/dali/) 
6. SCOP2 (randomly sampled SCOP pairs aligned using MMLigner at https://lcb.infotech.monash.edu/mmligner/)
------------ (SCOP from https://scop.berkeley.edu)

Benchmark 1-4 provide multiple alignments. All possible pairwise alignments were
generated from them.
