Huggins Closed Captures_Robust Design_Error message

[jackieguzy]

Hello,

I am getting the following error message when trying to use Robust Design, Huggins Closed Captures: "Internal error in CREATEPIM: Parameter=Gamma' nCols=0 nRows=0". I have 2 primary sampling periods and 5 secondary sampling periods for a total of 10 trapping occasions (semi-aquatic turtles). I have carefully checked my .inp file and found no errors (i.e. no missing data- 10 occassions for each animal, and no animals with 0 captures). Almost always, it ends up being my fault when I get an error (usually a problem with the .inp), but I can't seem to locate any .inp errors.

Must there be more than 2 primary occasions? Does anyone have other information?

Thanks for any help provided,

Jackie
