Hi Paul,
I used to use the following text to create a custom menu that I would
load into O (i.e. as a ".omac" file). The command I think you are looking for
is "trig_refresh". Once you defined a distance and/or angle, activate the
trig_refresh and then as you move atoms/pieces around, the distances/angles are
updated.
menu centre_id on ;
menu trig_refresh on ;
menu dist_define on ;
menu angle_define on ;
menu grab_atom on ;
menu grab_group on ;
menu clear_flags on ;
menu clear_id on ;
menu @add_water on;
menu refi_fix_atom on;

Subject: [ccp4bb] Model Building: continuous update of distances as fragment
moved
In doing some model building I want to move a domain of a protein
manually, as a rigid body, and see in real time continuous updates of
some distances from points on the domain to the rest of the protein (we
have cross linking data).
I dimly remember being able to do with this O,at least a decade ago
(probably more), but it doesn't seem to work in current versions (I
have even dimmer recollections that this might have been a special
feature of a particular graphics card in an SGI)
In any event, does anyone know of anything that might allow us to do
this? { I am not asking about computational ways of exploring alternate
packing of the domain to satisfy distances ( I know about these) -
rather we want to get a feel for what is possible by "seeing" it for
ourselves).
