Which protein force fields are compatible with GLYCAM?

This is actually two different questions. Both will be addressed here. Question 1:  In a simulation, which protein force fields behave well with GLYCAM? The GLYCAM force fields are designed to be independent of other biomolecular force fields, and, therefore, to work at least reasonably well with any of them.  The philosophy is that if […]

How can I use GLYCAM files in the oldff directory?

This question refers to the leaprc files stored in $AMBERHOME/dat/leap/cmd/oldff in distributions of AmberTools. Before answering the question, it is important to know that files in the oldff directory have been placed there because they are no longer recommended.  It isn’t necessarily that those old force fields are terrible; it’s just that the newer ones […]
