Hi All I'm getting an error refining with TaBr. Got tbr_exp.pdb from Hic-Up and prepared the cif with phenix.elbow. Try to do a refine with the pdb and cif and I get this error. Sorry: Conflicting scattering type symbols: initial symbol: "TA" (from pdb element column) new symbol: "T" (with residue name TBR) atom: "HETATM 1917 TA1 TBR B7131 .*. TA " What are people calling their TaBr records and/or how are they generating their cifs?
