Dear Ramon,
Thanks for bringing up the issue of downloading 3DNA v2.0. Dr. Olson is the proper contact for further instructions. Rutgers has imposed some licensing policy that is beyond my interest to get a hand on. Here is an excerpt, verbatim, of the message I sent to Dr. Olson regarding the release of 3DNA v2.0, after I uploaded the distribution tarball files for the most common operating systems (that I have access to) to the server in a password protected directory:
It is quite a while since our 3DNA NP paper was published. Over the
time I have received a couple of requests to download 3DNA v2.0
mentioned in our paper. Due to (complicated) license issues, I think
you are in a position to handle this issue. By getting more directly
involved, you would understand better what it means to maintain and
support a software.
As far as what's new with v2.0, it has already been mentioned in
http://3dna.rutgers.edu/. To recap, v1.5 as currently available in
http://rutchem.rutgers.edu/~xiangjun/3DNA/download.html was compiled 6 years ago that had never been updated. Of course, it still serves the majority of common cases very well, and I have used it as a test case of how robust my original implementation is (which is quite assuring, BTW). Of course, over the years, I have fixed bugs, added new features, and updated 3DNA to handle the remediated PDB files etc, which I have communicated with users on a case-by-case basis. The v2.0 contains an accumulation of all these refinements. More importantly, in writing the
3DNA Nature Protocols paper, I have added more command line options, new scripts and worked examples (
NP_Recipes.tar.gz). Accurately reproducing these examples and understanding how each works, users would see why 3DNA is called 'a
versatile, integrated software system for the analysis, rebuilding and visualization of three-dimensional nucleic-acid structures' . Aren't these sufficient reasons to upgrade?
