median c hat error Parameter Matrix not correct length

[lilypea]

Hi -

Does anyone have experience with this error, when trying to do median c-hat simulations for with a particular model?:

Parameter Matrix not the correct length in output:S
Returned length=630
Expected length =595

I'm importing my general model (LD data type, Burnham) from RMark into Mark for the median c-hat simulations. This model converges in RMark.

To note, when the model is imported into the results browser in Mark, the number of parameters are wrong (21), I adjusted them to 23. I get the above error whether I adjust the parameters or not.

Any suggestions?

thanks
