Mole=Q is Virtual Molecular Structure Model Software useable without licenses fee.
It can rendering the molecular model by just putting the molecular format.
And also it can select any image for background, so super-in-pose function is available easily.
Input Format ::xyz, car, cml, mol, sdf
Rendering Format ::Ball&Stick, VDW, Liquorice Stick, Z2A, ZC(HN), ZC(LN)
Note) The ZC model (Z-correlated molecular model) is the latest molecular model proposed by Eiichi Nakamura Laboratory of the University of Tokyo.
The implementation for this software was supervised by Senior Researcher Harano of the National Institute for Materials Science.
