This is a list of all pseudo atoms in the model. See section 5.3.2 for more information. Note that the list can only be appended to, and not reordered or deleted; this is to prevent restraints defined on the pseudo atoms from becoming invalidated. (You can call restraints.clear() to delete all restraints, including pseudo atoms, and start again if you need to delete pseudo atoms.)
Example: See Section 5.3.2 command.
