error when doing fit model

[TGfield]

Dear professor: the software is very useful. there has some little problem when i first using. I found that there is an error pops up immediately after starting the fitting routine: "Function error Error in script: averageDistance at line: 26 Undefined function 'gcp' for input arguments of type 'char'." Also, when i try the model selection(MAP), the another error shows: "Function error: Error in script :optimset at line :147 Default options not provided, function "isqnonlin" not present in path"

I use the last release of StatStem. The Matlab version is R2020a. Hope to get your reply ! Thanks

Hey TGfield. I also just started using StatSTEM and encountered the same issue. After some searching, I found out that first error occurs when the Parallel Computing Toolbox is not installed. I also found that a few other toolboxes are required, see quote below:

It seems like you are missing required matlab toolboxes. You'll need the following add-ons:

* distrib_computing_toolbox

* image_toolbox

* optimization_toolbox

* statistics_toolbox

You can install additional toolboxes under the "Apps"-Menu, then "Get more Apps" and find the toolboxes you need:

Perhaps the second error is due to the optimization toolbox not being installed; hopefully installing all of the necessary toolboxes solves your problem.
