Dear CCP4BB,

I'm trying to write a simple python script to retrieve and manipulate PDB data using the following code:

#for line in open("PDBfile.pdb"):
#    if "ATOM" in line:
#        column=line.split()
#        c4=column[4]

and then writing to a new document with:

#with open("selection.pdb", "a") as myfile:
#        myfile.write(c4+"\n")

Except for if the PDB contains columns which run together such as the occupancy and B-factor in the following:

ATOM    608  SG  CYS A  47      12.866 -28.741  -1.611  1.00201.10           S  
ATOM    609  OXT CYS A  47      14.622 -24.151  -1.842  1.00100.24           O 

My script seems to miscount the columns and read the two as one column, does anyone know how to avoid this? (PS, I've googled this like crazy but I either don't understand or the link is irrelevant)

Any advice would help.
Thanks for your time,
Grant
