Indicate the atoms to search for in the pdb file. One entry per line, keys are amino acid and atom. The minimum is 3. For ice this value should be the number of atoms in the list above. 3 Indicate the distance constraints which must be satisfied between each pair of atoms in the plane.
First entry is lower bound, second entry is upper bound.
There should be 'num choose 2' entries. Atoms on the plane are also selected. This can potentially lead to alot of out- put. Otherwise, only print atoms which meet distance con- straints and which lie in the same plane. Print entries in pdb file which match user's search key.
