$RandomizedR is a special command to setup the random alloy structures. The format is

$RandomizedR
Region_Number_used Random_type location_N_used seeding_num
location_1 location_2 ...... location_N
Region_1 method P1 P2 P3 P4 P5  .... 
Region_2 method P1 P2 P3 P4 P5  .... 
...
Region_N method  P1 P2 P3 P4 P5  .... 
Method=0 fully random number
Method=1 P1=dx(um), P2=average_com, P3=sigma, P4=indium_low P5=dn
Method=2 P1=dx(um), P2=average_com, P3=sigma, P4=indium_low P5=dn
The difference between 1 and 2 are Method 2 will not replace the trap related coefficents, nonradiative lifetime, doping, impurity, and generation of the original region. 

Example:


$RandomizedR
6 1 20 -10
13 14 15 16 17 18 19 20 21 22 23 .... 32 
3 0                                       (QW location)
5 0
7 0
9 0
11  1  2e-4  15  6.8e-4 0.01 0.02
13  2  2e-4  15  6.8e-4 0.01 0.02         # use the original lifetime, doping, , impurity, traps, and generation of the original region.
