problem error message

[Alexlyon]

hi

I'm using E-Surge for fitting multi-state models:
The models are built as follows:
-one initial state matrix
-one transition matrix divided in three step (survival, mortality causes and movement between three sites)
-one encounter matrix

My data consists of 45 capture occasions, 190 individuals, 6 groups, 7 events and 7 states (including 3 newly dead states: state 4, 5 or 6).
Typical encounter histories may be
01110202220003323214000....
00221002222222332200050....

I have no problem with computing the transition matrix in GEPAT.
I have no problem with computing the first initial state matrix in GEMACO too.
However when I want to build the first step transition matrix (survival step), E surge sends me an error message like that:

"(...)
this error was detected while a MEX-file was running. If the MEX-file is not an official MathWorks function, please examine its source code for errors
(...)
??? Error using ==> waitfor
Error while evaluating uicontrol Callback"

I would know what does this message mean, whether this error message rises from a bad syntax in the GEPAT matrix, a bad syntax in GEMACO, or because of a great number of "0" values in capture histories?

thanks in advance

Hello,
There is too few details before the error.
What is the phrase for survival in gemaco ?
Sincerely,
Rémi

Hello,

sorry, the error message was too long.
The phrase for survival was the simplest as possible:"from.t"
when I used the phrase "from", Gemaco computed the survival matrix but it did it slowly (may be more than 20 minutes)

actually, I already achieved to compute one time the survival matrix without any error message, but this error message arose then when I pressed the gemaco button for the mortality step.

In other words, it seems this error does not appear systematically.

Maybe I mistake in building the encounter histories and the corresponding transition matrices. But I suppose Gemaco will still constrain the matrix...

thanks again

sincerely,

Alexis

Hello,

I send this post to inform that I have identified the causes for the error message from MATLAB.
Actually, I read and read again the E-Surge manual and I stopped at the sentence, apparently anectodal "The choice of an appropriate number of age classes leads to a faster algorithm and is thus recommended if appropriate" p 40.

So, I changed the number of age classes from 48 to one, and then, I have no more problem to constrain the transition matrices and Gemaco run faster!

Any sentences is of importance !!

thank you and sorry for those who spent time on my problem
