Hi >From Justin: " Yes, as long as those atoms are listed as bonded within the [ bonds ] section of your .top file. "
The specific "bonded function", such as gb_28", should be also listed on the [bonds] section, right? Or, it could assign NOTHING for me, right? so, [bonds] ; ai aj funct 8 9 gb_28 is correct....... [bonds] ; ai aj funct 8 9 is INCORECT....... and 8 , 9 will NOT be automatically bonded, right? The same for the nonbonded parts, right? Thank you Lin On 9/22/08, Justin A.
