Re: [ccp4bb] Help with coordinate file

Hello Mona, I am guessing you have the atom name,number and coordinates in your file. I did something like that and Openbabel will convert it to the pdb file you desire but as far as I know, you will have to assign a residue name to the atom yourself. I did this by superimposition on the original

You might need to make sure that the input format you are entering is the correct one for the program that created the file. Thanks for the advice everyone. I downloaded the graphic interface for Open Babel but for some reason it's not converting my file. I'll play around more with this

Re: [ccp4bb] Problem on creating a new monomer

2007-05-07 Thread artis
Hi XJXJ, Did you create a library for this yourself? If you fix the ligand into the density and use those coordinates to create a monomer library for it in refmac, and use this during refinement, it might let it stay that way. Arti Hi there, I am trying to build a new ligand that I need to put

Shelx can refine occupancies. Arti Does anyone know a program can perform the ocupancy refinement? Or we always only refine B factor to reflect the occupancy? Thanks On 4/30/07, Eleanor Dodson [EMAIL PROTECTED] wrote: Well - it is extremely likely that the peptide is partially occupied

Hello Yingjie Peng You can do this in SPOCK. You can select all the residues that make up the pocket and select calculate, volume from the menu for these residues. Hope this works. Arti Dear all, Is there anyone who can tell me how to calculate the volume of substrate binding pocket in a

[ccp4bb] SHARP question

2007-03-26 Thread artis
Hi all, I am a first time SHARP user. I have it installed on SUse 10.0 OS and configured to ccp4-6.0.2. I do not see the option for inputting known phase information from my .mtz file on the Global page, even if the mtz file has the Hendrickson-Lattman coefficients. Also, in the Phase improvement
