There is a log attached in the first e-mail.
My first reaction was the same. Why 14 :).

Ah, that would make sense. May I suggest a tip to all users: don't send attachments when it is just as simple to copy and paste text into an email. I often see small attachment files in emails (footers, images, etc) so I ignore them. Also, don't send attachments without extensions. Names like "system" might look suspicious (especially someone like me who is cautious, knowing nothing about the level of security on your machine). Use obvious names, like "output.log" or something, if you must.

But yes, 14 is indeed correct in this case :)

        Hi,

        You should add 14 cl ions.


    Why 14?  The number of Cl- ions that are necessary is pretty much
    spelled out by grompp, and the net charge of the system is printed
    in the .top (qtot section in [atoms]).  If your system has a net
    charge of +2, add 2 Cl- ions, and so forth.
