[Chimera-users] preserving the serial numbering

[Eric Pettersen]

Hi George,
	The short answer is no.  Generally speaking, unless your structure is  
unmodified (in which case, why not use the original file?) there is no  
way to write a standard-conformant PDB file while preserving original  
serial numbers.  Let's say you opened a structure, added hydrogens,  
and wanted to write it out with unchanged serial numbers.  Well, the  
hydrogens are going to have serial numbers larger than any heavy atom,  
so since they will be written along with their residue-mates in the  
file (else TER card conventions would be violated), the serial numbers  
will not be... serial.
	Nonetheless, I can imagine scenarios where you would be willing to  
ignore the not-strictly-legal nature of such a file, so I'll add a  
feature-request ticket to the Chimera Trac database with you on the  
recipient list.  If anyone else would also like to be on the  
notification list, send me an email...
