Hi Sheng,
For your first question, since I never got the error "Assertion `dataset
>= 0' failed", I can't say too much about it.
About the group frequency, you may try the example "LaserSlab" (section
25.7.5 in the flash user's guide) or look at the flash.par in that
example. Following are the section in my flash.par . The group bounds
(rt_mgdBounds) needs to match what is given in the table. You can find
the format of the table in section 21.4.3 in the flash user's guide.
Cheers,
Po-Yu
