Dear Amber users,

I am using FF10 force filed to make parm and crd files. When I tried
to save the parm and coord files after neutralizing and solvating the
system its give an error with this message

Checking Unit.
Building topology.
Building atom parameters.
For atom: .R<Na+ 438>.A<Na+ 1> Could not find type: Na+
For atom: .R<Na+ 439>.A<Na+ 1> Could not find type: Na+
For atom: .R<Na+ 440>.A<Na+ 1> Could not find type: Na+
For atom: .R<Na+ 441>.A<Na+ 1> Could not find type: Na+
Parameter file was not saved.

Also when i used the commad xleap -s -f leaprc.ff10, its seems to be
first loading leaprc.ff03.r1, then its loading ff10.. Y is this ?

Thanks
