lDDT Local Distance Difference Test

This is the original implementation of lDDT, from 2013.

You should instead be using version 2.0, now incorporated into the Structure Assessment tool!

The local Distance Difference Test (lDDT) is a superposition-free score which evaluates local distance differences in a model compared to a reference structure. Please provide model and reference structures (using identical numbering of the amino acid sequence):
