A program for the computation of helical parameters from internal coordinates.
A method for the calculation of helical parameters from internal coordinates of an arbitrary repeat unit, has been implemented in a FORTRAN IV program. The coordinates of all atoms in a cylindrical coordinate system are also obtained.  An application of the program for a systematic approach to the problem of protein-DNA recognition is introduced.
