Re: [ccp4bb] How to generate a complete viirus PDB
Hi, In continuation to the previous suggestion about using the 'Oligomer Generator' in viperdb. To use viperdb, your pdb needs to be in the viper format. So download any pdb (example this one : http://viperdb.scripps.edu/cgi-bin/viper_coord.cgi?VDB=1z14) and then superpose your monomer onto this reference viper format pdband then upload your 'moved' pdb into the Oligomer generator 'browse' option. Then select the T number and the option for 60mer, 30mer etc. If this is an already published pdb then just input the id in the homepage and then the next page will have options for you to download a whole capsid or half capsid. -Tina On Thu, Apr 25, 2013 at 2:48 AM, Bradley Kearney bmkea...@ncsu.edu wrote: Hi Hong, ** ** I would recommend that you check out the services at the VIPERdb website http://viperdb.scripps.edu.

[ccp4bb] phasing with EM map using Amore
Hi, I am trying to use a cryo-EM map as a MR model for an Xtal data set. I have calculated structure factors for my map using SFALL. And then used rotcross function and translation function searches (from AMORE) to determine the MR solution. So, finally I got X, Y, Z fractional coordinates and Euler alpha, beta , gamma. Usually I start with a coordinate file (pdb) as a model whereas my initial model is a map. So how am I supposed to apply this solution to the mtz file from my initial map? Is there is a program/script available that can be used to apply those rotations and translation to structure factors ? Or am I proceeding in the wrong direction? I tried to use Phaser and Molrep but it did not give a solution. Any help would be highly appreciated. Thank you. -Sujata Halder
Re: [ccp4bb] strict structure based alignment
Hi, SSM (via PDBefold) (http://www.ebi.ac.uk/msd-srv/ssm/cgi-bin/ssmserver) will do a structure based alignment and outputs a table of rmsd but will not give you a alignment file as such. -Sujata On Fri, Jul 13, 2012 at 10:30 AM, Christian Roth christian.r...@bbz.uni-leipzig.de wrote: Dear all, I want align a couple or protein structures by secondary structure matching to one target and want get a kind of aminoacid alignment file e.g. what residue fit the other, without adjustments due to sequence based alignments. I tried Strap, but as far as I understood it, it takes also the sequence into account. I tried also Rapido, but this does only a pairwise comparison. Superpose does align it nicely (ccp4 based or Coot based) but there seems to be no option to print the sequence alignment in a file and it is again just a pairwise comparison . Is there an other program which does something similar? Best Regards Christian

Re: [ccp4bb] how convert SF to intensities
Hi, Use SFALL to convert coordinates to structure factors...and then use mtz2various to convert to intensities...use the scalepack format under mtz2various.
