Dear CCP4ers, I am attempting to build a short loop section into a low resolution map (4.5A). The electron density is clearly present but the low resolution is making it difficult to fit anything with sensible Ramachandran angles. Does anyone know of a program that will generate a series of potential loop conformations that I can compare against my map so that I can at least start with reasonable geometries? I have already tried the Fit Loop algorithm in COOT without success.
Many thanks Steven Glynn
