Hello
I am running mmpbsa in amber18 using the following command" MMPBSA-1.py -O -i mmpbsa.in -o mmpbsa.dat -do final_mmpbsa.dat -sp com_solvated.prmtop -cp com.prmtop -rp ras.prmtop -lp raf.prmtop -y md.crd"
But I am encountering an error which says "Loading and checking parameter files for compatibility...
sander found! Using /mnt/disk1/software/AMBER18/amber18/bin/sander

raise InternalError('Cannot pass no mask to Strip!')
InternalError: Cannot pass no mask to Strip!

How to rectify this kindly help as I am badly stuck in this.
Thank you,
Regards
