### Different output with newest version

Posted:

**Sat Aug 28, 2021 7:22 pm**I recently downloaded the newest version of Presence (13.12), and opened up a .pa3 file from a previous project I ran in 2018 on version 11.3. Everything opened fine, my data looked ok, and the last models I ran were showing up just as I had left them. When I go to run a new model, I noticed I was getting SEs of 0 for everything. So I ran a previous model, and just changed the name. I used the retrieve model option to make sure it was exactly the same. With the output, I get the same values for everything (AIC, w, parameter estimates, etc) except the SEs and CIs (all set so that SEs=0).

I looked more closely and noticed a couple of different things with the output. In v11.3, I get this:

But in v13.12, I get this:

The number of states have changed, both were ran as simple single season.

Other different output in case that's helpful:

v11.3

v13.12

and also this statement that I have not seen in the previous version:

Apologies if this is not a software/glitch issue, but I was wondering if something has changed between the versions where perhaps now I have to change how I enter/run the models, or if there is just some sort of error happening. I tried running other pa3 files from the previous version and I'm getting the same issue. Thanks in advance for any guidance.

********* Input Data summary *******

Number of sites = 162

Number of sampling occasions = 4

Number of states = 0

Number of missing observations = 0

Data checksum = 15524

But in v13.12, I get this:
