1. Input structure format

If you upload a file with one of these extensions, this value will be set automatically.

2. Auxiliary options

If the input structure is a 2D structure, you can check this box to get a 3D project of the structure:

If hydrogen atoms are missing from the structure, you can check this box to add hydrogen atoms:

3. Upload or paste input structure

Upload a structure file (one compound per submit):
