CMol is an interactive 3D molecular viewer designed specifically for the iPad, iPhone and iPod touch. CMol allows the user to open and view PDB files with complete control over the representations and colours used for individual chains, residues and atoms. CMol is the first iPad app to provide cartoon and ribbon view, transparency and slabbing for viewing proteins.

Features include:

- Defining selections based on chain, backbone, residue, element or HETATM status

- Colouring of selections from a wide range of available colours including rainbow and B-factor colouring

- Representation of selections (ball-and-stick, spheres, ribbons, sticks only and cartoon representation)

- Ability to vary the transparency of the selection

- Save custom appearances of molecules for loading later

- Downloading using the PDB structure ID directly, searching pdb.org for new molecules or importing custom PDB files using "Open with" functionality

- Control over slabbing (near and far clipping planes) of the view to provide clarity to the molecule

- Ability to change background colour

- Scaling of sphere and atom sizes

- VGA connection support

CMol provides:

- Beautiful rendering using in-built OpenGL lighting to provide depth to molecules

- Documentation so you can get the most out of the features of CMol

- Support for viewing both x-ray diffraction-derived models and averaged NMR structures

- Options to leave out certain view representations for rendering very large molecules

- A website with the latest technical support information about CMol

- Contact to the developer at support@cmol.org.uk

This app performs well on the iPhone 4. Although it has support for iPhone 3G and has been tested on it, the power of this device means that it is best to view molecules in cartoon, ribbon and sticks-only form rather than large amounts of ball-and-stick or sphere form. The time it takes to load molecules is greater than on the iPhone 4 or the iPad.

If you have any questions before you buy, please contact me on the support email address! I am happy to clarify the capabilities of CMol if there are any queries.

You can view the entirety of the documentation on the support website, http://www.cmol.org.uk - along with further images and extra information.

What's New in Version 1.3.3

Bug fix: no longer stalls on 'generating helices' while loading certain PDB files.
