conformation generation from internal coordinates



 Hello,
 is there a program, that generates conformations from distances,
 angles and dihedrals if they are not given as a complete Z-Matrix
 (e.g. mopac input) ? It should use additional angles instead of missed
 dihedrals and detect or handle incomplete determination of the
 conformation.
 My actual problem is a conformation described in an article using only
 distances and angles and I want to generate either a PDB or a MOPAC
 input file. I guess the given values are not sufficient to determine
 the conformation.
 Any suggestions would be appreciated
 Thank you
