UNAFold may be downloaded from the ibridge web site. You may find the software by entering "UNAFold" in the SEARCH area, or by going directly to the UNAFold URL at ibridge. You must register on ibridge before you can access license information, download the package or contact the Office of Technology Commercialization at Rensselaer Polytechnic Institute for additional information.

UNAFold 3.8 compiles on Linux, FreeBSD, IRIX, Solaris, AIX, Windows, Mac OS X and probably other operating systems.

If you are running Linux or Windows on an x86 processor, the binary distributions (RPM for Linux, EXE for Windows) should be used. For other platforms, or if you want to compile the software yourself, use the source distribution in tar/bz2 or tar/gz format.

Requirements: Perl 5.6.1 or greater is required both to build and to run UNAFold. In addition, there are several other programs/libraries which extend the functionality of UNAFold if detected:

• glut/OpenGL - for interactive graphics in hybrid-plot
• GD Library - for static graphics in hybrid-plot-ng
• gnuplot - for plots in hybrid2.pl

mfold_util is an optional add-on package with programs to view structures (.ct file input) and various dot plots (.plot or .ct file input). Binaries are available for Linux and Mac OS X. (The Windows installer for UNAFold includes the mfold_util binaries as well, so Windows users need only run the EXE below to get a fully-functional installation of UNAFold and mfold_util.)

Man pages for the programs in UNAFold are available online here.

A note for Windows users: UNAFold, like most Unix software, is command-line oriented — there is no GUI. After you run the installer, you will have to open a command prompt and run UNAFold.pl, hybrid2.pl or one of the other programs. You'll want to refer to the online man pages since the documentation installed with the software probably won't be readable under Windows.
