What Free Ubuntu-Compatible Software Exists for the 3D Visualisation of Biologic Proteins and Peptides? I asked this question https://chemistry.stackexchange.com/questions/4543/what-free-linux-compatible-software-exists-for-the-3d-virtualisation-of-biologic? but it got closed because it was software recommendation which is off-topic for chemistry stackexchange but I thought it wouldn't be off-topic for here. I am running 32 bit 12.10 if it is relevant.
Check out JMOL. It's open source and Java based - so it will work on Windows, Mac, and Linux. I just spent the last 20 minutes looking a superb model of ATP and a list of other molecules in crosseyed stereographic 3D!

There are a few different softwares for this kind of modelling that will work on Ubuntu including:
My personal preference would have to be either Jmol or MarvinView.
