Hello everyone,

I’m working with Materials Studio, and I generated an amorphous cell containing H₂O, a protein, a ligand, and several ions. I exported the structure as a PDB file, intending to use it in Discovery Studio.

However, I noticed something strange — the water molecules don’t appear correctly when I open the exported PDB file in Discovery Studio.

I’m wondering:

• Are there specific considerations or settings I should be aware of when exporting from Materials Studio to PDB format for use in Discovery Studio?
• Is there a better file format to use for compatibility between these two programs?
• Has anyone else experienced similar issues with water molecules not displaying properly?

I’m not sure if this question should go under the Discovery Studio forum or somewhere else, so I’m posting it here for now.

Any help or suggestions would be greatly appreciated. Thank you in advance!
