The default file format for trajectory files changed in Amber16 to netcdf.
This is probably the reason for the file size change; I don't know if
mmpbsa handles netcdf files or not, but the error message quoted above
is at a place where the code is expecting to find the older format. Set
ioutfm=0 if you want to go back to using ASCII trajectory files.
