Dear gromacs users,
Thank you for your answering my previous questions.
Here, I am in trouble again.
I continue the simulation of DNA, carbon nanatube and water.
I changed the names of atoms in cnt.pdb according to the names in
When I performed the energy minimization, the result I get is :
Invalid order for directive defaults, file ""ffamber99.itp"", line 4".
I checked back ffamber99.itp, the whole file is simple :
[ defaults ]
; nbfunc comb-rule gen-pairs fudgeLJ fudgeQQ
1 2 yes 0.5 0.8333
Can you give me some suggestions and help me out?
Also, I have a question regarding the residue names in amber99.
I guess that I may also need to change the residue of CNT(carbon nanotube)
according to the residue names used in ffamber99.
Do you think that it is necessary? And, how can I do it?
Thank you so much!
