Hi Marcelo,

...

I'm refining a protein structure with a cysteine covalently bonded with a fatty acid. However, this cysteine has a double conformation. I try to make a link with "cif_link.params", but I don't know how to describe the double conformation. How can I make this link between the fatty acid oxigen and the sulfur of the cysteine in one of the conformations?

You can use e.g. "altloc A" and "altloc B" to distinguish the conformers. Let me know if this doesn't help.
