Hi Daniel
Usually AT and GC are considered as H-bonded but, e.g., A can have H-bonds with C also. Does natstruct consider this? e.g. If DNA structure distorts and goes like this does it consider H-bonds for A-C?

#normal        #wrong base-pair
                         -T
A-T               A-C  
G-C    ===> G-A
T-A               T-G
C-G              C-

thanks
Jiom

Hi All,

I would like to announce update 24 for AmberTools 13, which contains minor
bug fixes for CPPTRAJ:

1) In 'nastruct', fix small error in calculation of number of hydrogen
bonds between base pairs; only affects first frame when the given residue
range is not continuous.

2) Fix a bug that was causing number of frames to be not properly detected
in Gzipped Amber trajectory files larger than 4 GB.

This update is currently available. To apply, simply re-run configure from
$AMBERHOME and re-compile.

-Dan
