[COOT] ncs ghost control

2010-03-01 Thread Eleanor Dodson

This seems to be lost ??



/y/programs/xtal/coot/coot-Linux-i386-fedora-10-gtk2-python/share/coot/python


reads pdb and says:

...


INFO:: NCS chain comparison 306/307

INFO:: NCS chain comparison 306/307
INFO:: NCS chain comparison 305/307

  Ghost 2 name: NCS found from matching Chain D onto Chain A
  Ghost 3 name: NCS found from matching Chain E onto Chain A
  Ghost 4 name: NCS found from matching Chain F onto Chain A
Molecule 0 read successfully


then reads some monomers
...

then
NCS_controller display chain toggled for imol 0 chain 1 state 1
 ncs_control_display_chain
There are 5 ghosts
 ighost: 0
name: NCS found from matching Chain B onto Chain A
 chainid: B
 target chain id: A
 display_it_flag 1
 ighost: 1
name: NCS found from matching Chain C onto Chain A
 chainid: C



...

then when I try to display it:

Admittedly the pdb begins with the ligand numbered 501 then goes back to 
1 2 3 etc..


Has that upset it??

That would be my guess - 60-70% probable I estimate - such is the nature 
of mmdb atom selection...
