CCL: force field of amber14

To whom it may concern,


This is Sulgi, a M.S. candidate and user of amber14.


I’m writing to enquire about force field of amber14.

When I tried to making new topology with my system, I read amber14 tutorials and did leap process using below command.


Tleap –s –f $AMBERHOME/dat/leap/cmd/leaprc.ff14SB

Source leaprc.gaff

Loadamberparams frcmod.ff99SB14


However, few days later, I found that force field reads parm10.dat.

When I used amber11, parm99.dat was in log file formed by leap.

Ph. D in my lab. let me know the right commands for ff99SB force field, but I am wondering if I can use my system based on parm10.dat.

Is it a big difference or serious problem between parm10.dat and parm99.dat??

What is differences between the two?

Could you please explain me?

(If I send mail to wrong address, then please let me know.)


Thank you for your consideration.
