Hi all,

    I see in the mm_pbsa_calceneent.pm file the following data for several
atoms/ions:

....
     # Prepare for calc of molecular surface
     %exp_rad = (
            "N" => 1.550 + 1.400,
            "H" => 1.200 + 1.400,
            "C" => 1.700 + 1.400,
            "O" => 1.500 + 1.400,
            "P" => 1.800 + 1.400,
            "S" => 1.800 + 1.400,
            "FE" => 1.300 + 1.400,
            "Na+" => 1.200 + 1.400,
            "Cl-" => 1.700 + 1.400,
            "MG" => 1.180 + 1.400,
           );
...

    But not for a calcium (KA) ion. As I figure these are radius data; I
wonder what might be a suitable value for KA.
    I want to make energy calculations with mm_pbsa.
    Yours,

Jorge
