LCore is a program for classification of 3D structures of macromolecular complexes on the basis of their geometric core.

Alignment (example):

Distance threshold (Å)
Minimal core size (#aa's)
Alternative core new atoms (%)
Max number of cores on output
Core identifier for chain superimposition (0 for the main core)

The service is created with support of Russian Science Foundation, grant no. 14-50-00029 (algorithm and testing), and Russian Foundation of Basic Research, grant no. 14-04-01693 (programming).
