Minimal distance between one atom and a group

Dear all,

Is there any easy way of calculating the minimal distance between one
atom and another group of atoms without too much calculation cost? I
checked manual, it doesn't help much on this question. Thank you very



You could define an atom-style variable that calculates
the distance between a specific atom and all other atoms.
Then use compute reduce
to take the min() of this atom-style variable on the group
of atoms you want.
