The problem when I used local Matlab to produce data

Due to the calculation speed, I used local Matlab to make model input data, but I encountered the following problems.
When I run “start”, there will be an error in on line 72 of the start.m file.

The array index must be a positive integer or a logical value.

error start (Line 27)
72 if (strcmp(mysystem(end-1:end),‘86’))

How can I solve the problem?Can I ignore start and just run make_grid?

I have solved the problem. 72 line relevant can be removed and the correct path needs to be added to the crocotools_param.m file. warning: windows users need to use ""
