Dear Amber users,

I searched the past archieves but couldn't find the relevant solution, so
writing it again.
I am facing bit complicated problem currently. We have some new MD software,
but it is not accepting .prmtop and .prmcrd files as input for running the
Instead, it says:

"To allow your AMBER-simulated systems to be run, coordinates and structure
files must be regenerated using VMD and the AMBER topology file in CHARMM
format, as all input files must be in CHARMM format."

Anyone has any idea how to deal with such case?

Thanking you,
