Re: [COOT] merge symmetry related atoms in coot

2008-08-11 Thread Eleanor Dodson

This is tricky I find ..

You can use the NCS ghost to fit the bits of A you like over B, then 
work out what bits of B you want to shift into A.


There are tools to rename that bit of B to A and if necessary renumber 
it as well..
Then output the renamed file and you will probably have to edit it by 
hand to get the fragments in the right order..

Hello

I have a partial model with 4 chains,  but some part of A chain is in B
chain, can I merge the symmetry  related atoms to make a right A chain?

Re: [COOT] to regenerate a pdb file from ssm matrix

2008-08-11 Thread Qing Chen
Hello Paul,

Yes, I did some model building using Coot only of chain A. I checked the
link, it is saying:
Note that you can currently only apply NCS edits to residues that exist in
the other chains. If for example, you had introduced/added residues 1 to 5
in the A chain and wanted to copies those over to the other molecules,
then that would not work
(88)http://www.ysbl.york.ac.uk/%7Eemsley/coot/doc/chapters/user-manual_fot.html#FOOT88
.

Since I did renumbering, adding ,deleting residues to chain A, so seems it
wouldnot work by apply NCS. Now I would like to run refmac5, so I need a
complete model, right?
I am a rather beginner, is there any better ways to rebuild in my case(4
molecules in one assymetry unit).
thanks

 Dear Qing/Jenny Flower,

 When you say I refined chain A, I am presuming that you mean that you
 have done some model building using Coot.  You then want to apply the edits
 that you have made each of the chains in your model (applying the NCS
 transformations as necessary):

 You should read the user manual, section 5.27 Applying NCS Edits:


 http://www.ysbl.york.ac.uk/~emsley/coot/doc/chapters/user-manual_5.html#SEC134http://www.ysbl.york.ac.uk/%7Eemsley/coot/doc/chapters/user-manual_5.html#SEC134

 In your case it seems that you want this function:

 (copy-from-ncs-master-to-others imol master-chain-id)

 HTH,

 Paul.

Dear Qing Chen,

Woops, sorry - the documentation is out of date - I'll fix it shortly. 
The copy chain makes exact copies of the master chain (with the NCS 
transformation applied obviously).


Which means of course, mutations, deletions, insertions will be applied too.

I have added a NCS copy chain function to Extensions as of revision 
1327.  That should help.

Re: [COOT] to regenerate a pdb file from ssm matrix

2008-08-11 Thread Qing Chen
Hi Paul,


I could not find  NCS copy chain function under my coot 0.4.1. I was trying
to update my coot using fink, but failed. So I did it in a maybe unusual
way:
1, I use SSM superinpose my A chain to B, C, D, accoring to the rotation and
translation matrix I got from coot , I run pdbset to creat chain B,C,D from
rebuilt-A chain one by one
2, then I open chain A and converted chain B,C,D in coot again and merged
then
It is a bit labourious.

thanks!

Qing
