[Pw_forum] Too many r-vectors?

[Harper, Lenora K.]

Dear Sir or Madam,

I am running a vc-relax calculation on an organic 78 atom molecular system under extreme pressure (50 kbar) and am receiving an error, "too many r-vectors." I see that my problem could lie in the fact that my cutoffs are too low. Which cutoff are we speaking of and what would be an acceptable cutoff for this type of system?

Thank you for your time,
