[ccp4bb] rearrange atom order in pdb file

[Kim, Eun Young]

Dear all,
 
In my pdb file, atom order of the residues are N, CA, side chain, C, O.
Does anyone know which program can rearrange atom order to N, CA, C, O, and 
side chain (which is a standard pdb format you can see from RCSB website)?
I checked 'pdbset', but could not find any option to change atom order. 
Thank you in advance.
 
Best,
Eun Young
