Dear Syed,   The diffraction pattern is a bit strange: the distant rows of very closely spaced spots point to a cell that has at least one long dimension (indicating protein), but the very strong isolated spots at mid-resolution indicate salt. Could there be two crystals on your loop by an

Dear All, I wonder if you could help me with this. I am trying to do some regularisation/real space refinement of a ligand with Coot. The ligand is a pseudopeptide with two non-standard aminoacids, followed by several standard ones. I assume that to do this correctly, I would need a cif file th
