Jian,


I have tested your script out.  I changed the subroutine to return a  
blank string; it was shooting off warnings when they were turned on,,  
but the results were the same w/o any warnings:

Use of uninitialized value in pattern match (m//) at
/Users/cjfields/src/bioperl-live/Bio/Structure/IO/pdb.pm line 449,  
<GEN0> line

SER-120.GG  <----
SER-120.HH  <----
PHE-120.II
VAL-120.JJ

Isn't the arrow pointing at SER-120G and SER-120H?

You might want to check that you are running the latest Bioperl  
release (1.5.2); I noticed that a CVS commit that may be related to  
this was made after the 1.5.1 release.  If you have upgraded, an  
older installation may be interfering.  You can check which version  
by running (I think this will work on WinXP):

perl -MBio::Root::Version -e "print $Bio::Root::Version::VERSION,\"\n\""

To locate your bioperl installation being used:

perldoc -l Bio::Root::Root
