Some of NEURON's GUI tools require that a default section exist before they are created. The PPM is one such tool. If you are writing hoc code, make sure that it creates at least one section and contains one "access" statement _before_ you try to use the PPM. For more information about the concept "currently accessed section" and documentation of "access" see
