See Nuccyl Home


nuccyl is a Perl program that allows PyMOL, a powerful open-source molecular modeling system, to display atomic models of nucleic acids in a highly simplified representation. By depicting the nucleic acid backbone as a cartoon and the bases of nucleotides as cylinders, similarly to the excellent programs Ribbons and Drawna, nuccyl and PyMOL allow to quickly grasp the overall folding of an RNA or DNA molecule

nuccyl produces base cylinder coordinates and command files to display them with PyMOL. The base pair analysis programs RNAView and 3DNA can also be optionally used to obtain starting input files for nuccyl.

RNAView can be downloaded and installed as described; a publication describing the program is also available. Information and download links for 3DNA may be found at the program's home page; a paper has also been published.
