Here the resolution cutoff has been reduced from 2.1 Å (which SHELXC would have suggested) to 2.0 Å to improve the chances of resolving the sulfurs. The SHEL, FIND, MIND and NTRY instructions are transferred to the file thau_fa.ins for the sulfur atom location with SHELXD. Note that the phases can be improved further in this case by using more SHELXE cycles than the usual 20. <br><br> | Here the resolution cutoff has been reduced from 2.1 Å (which SHELXC would have suggested) to 2.0 Å to improve the chances of resolving the sulfurs.

will use exp1.hkl, exp1_fa.hkl, exp1.ins (as above) and will try 3 cycles of backbone building. | |||
