Dear all, using refmac5 to provide H-atoms for a protein structure the distance between CYS-CG and HG is defined to 1.34 Ang. in CYS.cif. That distance has been mentioned by a non-CCP4 program by * Poor covalent bond length of 1.33954 for hydrogen atom ....
In an other library-file CSH.cif the same distance is defined to 1.1 Ang. What is the correct one? Could you comment on this? (Of course I know hydrogens will not be refined ...). Thank you, Juergen
