Unfortunately, NCBI can no longer support a Unix version of the newest Cn3D software. However, an earlier release, Cn3D 4.1 for Unix, is still available from this page by following the instructions below.
Download the appropriate version:
- Solaris. Requires Solaris 7 or higher, and Solaris OpenGL.
- i386 Linux. Requires system-installed shared libraries of GTK 1.2.7 - 1.2.10, and standard image libraries (libpng, libz, libjpeg, libtiff).
- SGI IRIX. Requires IRIX 6.5, R5000 or higher CPU.
Then complete the following to extract and install Cn3D:
- Unzip the archive with
gunzip Cn3D-4.1.????.tar.gz (if your system doesn't have gunzip, use gzip -d ... instead).
- Type
tar -xvf Cn3D-4.1.????.tar to extract the Cn3D-4.1 folder, which will contain the Cn3D executable, the data directory, and the help file. - Set the CN3D_HOME environment variable to your Cn3D-4.1 directory. For example, if you are using (t)csh, you can put
setenv CN3D_HOME /home/myuserid/Cn3D-4.1 in your .cshrc file.
- Optionally, you can put Cn3D in your $PATH, for convenient startup.
Once done, see the instructions on configuring your browser.
