If there is no convergence the algorithm proceeds for up to 64 iterations. It's usually sufficient to get close to a local peak. This number can be increased in script by setting DCM.options.Nmax to a higher value.

Dear DCM people,
what happens after 64 iterations in DCM for ERPs? I do not get the message of conversion and the iterations stop.
