hello,

could anybody confirm, that rigid body refinement
in ccp4i/refmac5 does work ?

in ccp4-4.1 i always got too many 'zero or negative things'
(whatever that means ...).
so i went to the 'competition' (cns) and did my work there.

now, in ccp4-4.2, i get NO changes in R-factor whatsoever
in the 4th decimal. epmr does have a good rigid body
refinement routine buit in. but NO changes in the 4th
decimal ... (except in the first cycle, where there is a tiny
jump)? and nothing else that looks
suspicious in the log file - at first glance, that is ...

of course, i can go to cns, again, but i am getting
somewhat curious now, what my problem might be ...
haven't dug around in the command scripts yet, everything
done from ccp4i.

greetings

ingo
