More than a decade ago, at the end of the 80's, the different molecular modelling programs have started widely to spread. These programs use different file formats to hold the coordinate and atomic data, and each formats follows unique syntax rules, which prevents the direct transfer of the molecules between the different applications. It was a serious drawback of the early programs, but even today there is a need for the transformation of molecule files. This led to the development of the original Mol2Mol several years ago.
主要用来进行各种分子文件的转换，支持30种主要分子格式，也可以用来进行3维分子的简单显示。可将PDB格式输出为POV格式后，用POV-RAY进行渲染，生成非常漂亮的三维图形。演示版只支持样板文件与原子数小于20的分子文件格式的转换。
