<p>I am currently working on a subpackage for Biopython (called
Bio.Structure), that converts a Bio.PDB.Model.Model into a numpy
array containing coordinates and annotations for doing easily
efficient calculations (for example calculating average
structure). This array can be converted back into a
Bio.PDB.Model.Model and than saved as PDB file using PDBIO().
Currently docstrings and code comments are missing, so I will
contribute this code only in a few days, but you can check out the
source code at

<div>I want to calculate the average structure from multiple
frames in a pdb file and save it to another pdb file.<br>
<br>
</div>
I wrote the code to calculate the average co-ordinates
successfully like below:<br>
<br>
#!/usr/bin/python<br>
<br>
from Bio.PDB.PDBParser import PDBParser<br>
<br>
import numpy as np<br>
<br>
parser=PDBParser(PERMISSIVE=1)<br>
<br>
structure_id="mode_7"<br>
filename="mode_7.pdb"<br>
structure=parser.get_structure<wbr>(structure_id, filename)<br>
model1=structure[0]<br>
s=(124,3)<br>
newc=np.zeros(s,dtype=np.float<wbr>32)<br>
counter=1<br>
fincoord=[]<br>
for i in range(0,29):<br>
coord=[] <br>
model=structure[i]<br>
for chain in model.get_list():<br>
for residue in chain.get_list():<br>
ca=residue["CA"]<br>
coord.append(ca.get_coord())<br>
<br>
newc=np.add(newc,coord)<br>
counter+=1<br>
<br>
fincoord=np.divide(newc,counte<wbr>r)<br>
<br>
print fincoord<br>
<br>
print "END"<br>
<br>
</div>
Now I want to write the coordinates in fincoord to a new pdb
file i.e. everything will be the same like the structure[0]
except the coordinates. Can you tell me how can I edit the
coordinates of a specific model or replace it with my array
and save it to another file?<br>
<br>
</div>
Thanks<br clear="all">
