('binary' encoding is not supported, stored as-is) Hi,

I try to use ptraj to measure the distance between two atoms. This is my input:

trajin model1-3-md1.crd
distance first out model1-3-md1-dist1.dist 84.ND2 197.O time 0.1
strip :WAT
go


But it is seems blocked somehow. Please help.

Bo

This is the output:

guanine.6% ptraj model1-3.prmtop < model1-3md1-dist1.in
