I am doing this for regular DFT, DFT+U and a non-collinear calculation with regular DFT and with U and J. For the regular DFT cases the plotbands.x works just fine giving me a ps file. But for the DFT+U and DFT+U+J cases I keep getting NaNs in the output for the same k-paths. I've read that repeating k values twice can cause this but I've checked my input and this doesn't seem to be the case. However, plotbands for some reason adds an extra high-symmetry point at the same x-coordinate :</div>
