HI3D is a Web app that allows the user to interactively index the parameters (twist, rise, csym) of a helical 3D structure. It generates a cylindrical projection of the 3D map, computes the auto-correlation function of the cylindrical projection, and then uses two distinct lattice identification methods to obtain a consistent solution of the helical parameters.
