Dear David
Actually I posted my doubt in Vol 28, Issue 38. There I detailed more. 


sorry, I don't memorize it all...

Anyway, my system is 1 C60 molecule in 1000 ethanol molecules. As said, 
I need of structures that do not remember the previous one, i.e. that 
are structural and statistically not correlated.
For this, up to now, I have attemped to use the autocorrelation function 
of the energy and the block averaging process, but I am still uncertain 
about the results.
An interesting option it could be the analyzis of van Hove function, but 
I dont kwow how calculate them.




You probably want to know a characteristic interaction time between the 
C60 and ethanol. Since this will be dominated by Van der Waals 
interactions you can try to compute the autocorrelation time of C60 - 
Ethanol-Carbon contacts (using the CVS version of g_hbond) and then

use something on that order of time.
