GRASP/DELPHI format



Dear all,
 we are interested in a routine to generate GRASP files from a previously
 calculated property at a grid of points. We have seen in the GRASP web page
 that the possible file to do this will have the format of a DelPhi
 binary potential map file. This can be found in
 http://honiglab.cpmc.columbia.edu/grasp/grasp_contents.html#read
 However, we have problems in understanding the meaning of some of the variables.
 Has anybody created such a routine?
