ATOM DIRECTORY: Printing

Any AtomGroup object can be printed. The output is one line per object. When a Group is printed, the descendants of this Group are also printed. The output for a large hierarchy may be unmanageable.

The output for an Atom node consists of:

{-}+{N}\t{1}:{2}\t{3}:{4}\t{5}:{6}\t{7}

{-}

a number of dashes that is one less than the level of this node in the hierarchy

{N}

The value of the nodename attribute

\t

Tab

{1}

The value of the atomindex attribute

{2}

The value of the reference attribute

{3}

The value of the mass attribute

{4}

The value of the charge attribute

{5}

The value of the atomitype attribute

{6}

The value of the atomxtype attribute

{7}

The value of the mask attribute

The numeric codes for the chemical state and atom class (positive or zero) are printed if they had been specified. Otherwise, -1 is printed if they have not been specified or -2 if an illegal value had been specified.

The output for a Group node consists of:

{-}+{N}:\t/{1}:{2}\

{-}

a number of dashes that is one less than the level of this node in the hierarchy

{N}

The value of the nodename attribute

\t

Tab
