Question about the TestProcess

[linjing7]

 Hello, thanks for your pretty excellent code. However , I have a problem about the TestProcess():
 The type is calculated by the following code: (line 108 in Test.py)
             t = ((offset2_i[0] - patchMargin) % R) * R + ((offset2_i[1] - patchMargin) % R)
 I think that it doesn't need to plus the patchMargin, for the reason that offset2_i is exectly the coordinate of the left-top point of the patch. Is it right?
