[gmx-users] Fatal error: Invalid dihedral type 0

[He, Yang]

Hi Mark,

I have carefully adjusted the parameters but it still doesn't work. I am confused about that because I just dealt with the dihedraltypes before in the same way and it works while for this time, something wrong happened.

Could you give me more suggestions about this/

Thank you

Yang

You should try to work out which line this relates to...

Yup - read the format description for these function types (e.g. Table
5.3 in the 3.3 manual). You're giving a set of parameters that do not
match your function types.
