>>> Is there any way to calculate fraction of native contacts during the
>>> simulation in gromacs. I searched the archives but didn't found any
>>> significant clue.
>> At present, there is no way to do this. Likely one could modify the g_mindist code to do this - it would be a very nice feature.
> If one could get the -sel option of g_hbond to work again then you would get such information with -contact.
In the meantime you might be able to use MDAnalysis http://mdanalysis.googlecode.com/ and the native contact analysis in MDAnalysis.analysis.contacts, see http://packages.python.org/MDAnalysis/documentation_pages/analysis/contacts.html
(If you have questions about MDAnalysis then please ask them on that project's discussion group http://groups.google.com/group/mdnalysis-discussion — people there are more than happy to help.)
