$usespecgen is the command to put generation profile with a specific function, which is mostly Gaussian shape generation profile.

 $usespecgen
 N_region
 func_type A B sigx, sigy, xc, yc


For function type 
 1: <math> G(x,y) = A*B * exp(-\frac{(x-xc)^{2}}{sigx^{2}}) * exp(-\frac{(y-yc)^{2}}{sigy^{2}})   </math>
 2: <math> G(x,y) = A*B * exp(-\frac{(x-xc)^{2}}{sigx^{2}})* exp(-\frac{(y-yc)^{2}}{sigx^{2}})* exp(-\frac{-|(y-yc)|}{sigy})  </math>
 3: <math> G(x,y) = A*B * exp(-\frac{(x-xc)^{2}}{sigx^{2}})* exp(-\frac{(y-yc)^{2}}{sigx^{2}}) * exp(-\frac{-|(x-xc)|}{sigx})  </math>
 4: <math> G(x,y) = A * exp(-\frac{(x-xc)^{2}}{sigx^{2}}) * exp(-\frac{(y-yc)^{2}}{sigy^{2}})   </math>
 5: <math> G(x,y) = A * exp(-\frac{(x-xc)^{2}}{sigx^{2}}) * exp(-\frac{-|(y-yc)|}{sigy})  </math>
 6: <math> G(x,y) = A * exp(-\frac{(y-yc)^{2}}{sigx^{2}}) * exp(-\frac{-|(x-xc)|}{sigx})  </math>
