You named your ions wrong. Please read the help information from genion -h:
"The ion molecule type, residue and atom names in all force fields are the
capitalized element names without sign. This molecule name should be given
with -pname or -nname, and the [molecules] section of your topology updated
accordingly, either by hand or with -p. Do not use an atom name instead!"
Note that, if you are referring to my "Tutorial 1" on lysozyme, the naming issue
is explained and the genion command should be copied verbatim, as I do not use
any +/- signs in the -pname or -nname options.
