Hi Rémi,

I am trying to fit multi-event models with E-surge for Windows 64. It is a huge model with 25 initial states, 4 transition steps (among them, two transition matrices have dimension 25*41 and 41*25) and 3 event steps with 5 possible events.

The model is huge because I have included trap-aware states to account for trap-dependence in the data.

Hence, the matrix dealing with trapawareness is the last transition matrix as R.Pradel and A Sanz-AGuilar did recently.

Gepat, Gemaco (albeit long) work well. I use initial values (using IVFV files) from previous betas of simpler models (so I used real axis). the IVFV step works too, but, as soon as I click on the run button, It get an error message in the black window:

here the beginning of the message:

"Error using reshape

To RESHAPE the number of elements must not change.

Error in modme/grad_F1_age_evt>gradPattern (line 723)

Error in modme/grad_F1_age_evt (line 683)

Error in modme /f_age (line 19)

[...]

"

what does it mean?

Is this due to a too large matrix dimension?

Could you help me please?

Best wishes

Alexis
