Dear CCP4BB,

I have come across a problem when running refmac5 in CCP4 6.1.1 via the
gui. I have a twinned data set and so want to refine the twin fraction
of the data. I selected amplitude based twin refinement in the gui, but
find that the resulting command file does not contain the twin keyword
and hence twin refinement does not occur. If I manually edit the
command file to include the twin keyword then refmac calculates twin
fractions etc. Has anyone else come across this problem and if so how
did you solve it?

best regards,

Steve Carr
