I get the following error messeage from openMX:

Error in mxModel("ACE", mxMatrix(type = "Iden", nrow = 4, ncol = 4, name = "I"), :

argument is missing, with no default

this "ACE" mxModel object contains only mxMatrix and MxAlgebra ellements.

It is one of six submodels in a bigger model this bigger model contains an mx Algebraobjective the other 5 submodels contain data and a mxFIMLObjective each for the different groups.

Which argument am i missing in this ACE mxModel? which are the required model arguments anyway?
