Main Features

Opening files
In ChopChopMol, there are multiple ways to open a file. It supports the XYZ, MOL2, and PDB file format as of now. You can navigate to the upload dropdown and select "Open File", or you can simply drag and drop a file into the page.
Selecting Atoms
You can select a single atom by clicking on it, or select multiple atoms by cmd/ctrl and clicking on multiple atoms. You can also use the box tool by holding cmd/ctrl and dragging to create a box and select anything in its borders. When you select an atom, it will be highlighted in yellow.
Using Axis tool
First, select 2 atoms in the molecule. You can create an axis in 2 ways:
  • Click on the "Create Axis" button
  • Press the space bar


After creating an axis, you can perform actions with it such as rotation, or translation reletive to the axis. You can rotate any selected atoms around the axis by using the slider, or by holding shift and scrolling with the mouse. You can also translate the selected atoms relative to the axis by using the slider, or by holding shift and dragging the mouse.
