this is the command to generate graphene sheets. difficult to do
nanotubes with it.
what do you mean by "other than CNT".

"does not work" is a useless description. it *does* work for me and
now this help you??

so you'll have to provide more details: what exactly did you do? and
what did you expect? and what did you get instead?

...and always specify which version of VMD and what OS you are using.

please me more specific or else nobody will be able to help you.
