Cgenff failed to make parameters for perchloric acid

Dear Gmx users,

I would like to perform MD simulations of a peptide in different solutions. I have perchloric acid one of the solutions. I tried to get the parameters of perchloric acid using CgenFF. However, it failed after upload mol2 file to the server. Do you know any other tools to create these kinds of parameters?

Best regards,

Mijiddorj
