Dear experts,

There are some errors when I open or run the stage 4, my computer system is windows 10 and GTG is GTG_beta_0.45.

1.Using matlab R2017a or matlab R2014b,I can not open the GUI fully(screenshot attached).

2.Using matlab R2012a, I can open the GUI fully but can not  use parallel processing. I know that PCT was not available until matlab 2013, but it doesn't work even if PCT Workers is set to 1, the following is Matlab error message(PCT Workers=1):

Undefined variable "parallel" or class "parallel.internal.convertStringToChar".

Error in gcp (line 38)
