OVERVIEW

• This template is inspired by QRChem by Professor Neil Garg and his QRChem team. However, this template allows users to upload their own structures and not just structures existing in Pubchem database.
• What this template is: This is a simple template for auto generation of QR code for uploaded molecules. This template does:
  1. Upload structural files to a pre-determined folder on server via http or https
  2. Generate a QR code to the 3D viewer (using 3DMol.js) for the uploaded files
• What this template is NOT: it does not optimize (i.e. energy minimization) the structure input so the structures will need to be optimized before uploading.
