Dear Amber users,
I used partially solvated like 'solvateCap test WATBOX216 { 1 -37 21 } 22'.
I'm now doing 'step 1 Heating up the system then MD under Constant pressure and constant temperature '
Is it possible to keep constant tempature in MD after heating to 300K from 100K?
Since there are no box informations in partially solvated system ,so 'NTB=1 and NTB=2' can not be used.
How to set the parameters in sander.Thanks a lot!
