How to make ISAM_REGIONS file?

@cjcoats
I have changed the input time,data,and timestep,tried again,but the 11mask’s contribution are all zero. So I 'll change the value of grids to be rounded to be the integer., and try again.
The following is my grids’svalue:
1, 1, 1001,1.00000000
1, 2, 1002,1.00000000
1, 3, 1003,1.00000000
1, 4, 1004,1.00000000
1, 5, 1005,1.00000000
1, 6, 1006,1.00000000
1, 7, 1007,1.00000000
1, 8, 1008,1.00000000
1, 9, 1009,1.00000000
1, 10, 1010,1.00000000
1, 11, 1011,1.00000000
1, 12, 1012,1.00000000
