[Pw_forum] SWCNT (6,6)

[zahra sadat naghavi]

Dear every body!
  SWCNT (6,6) is a metal but I have plot its band and found a 0.2ev-gap between the bands which must visit each other at fermi enery. people say that there is something wrong with my pseudo potential which  psedo potential should I select?
  An other problem is that the rang of energy must be (-10,-10) but I found it (-19,7) in dos and band structure!
