Hello,
we are currently running some gas-phase simulations of ATP and related
molecules with Sander. We appear to be having some problems whereby within
one time step of a given simulation the Ribose ring changes to another
diastereoisomer. This seems rather strange as it strikes us to be a
physically impossible change.
We would like to know if anyone has encountered a similar situation, and if
anyone knows how to ensure that this change cannot occur. We have already
tried running Sander with a variety of temperatures, time steps and other
parameters.
Many thanks,
William Boxford,
University of York.
