VASP and ABINIT give different bandstructures?

Dear all, I tried to plot the electronic bandstructure and electron DOS with ABINIT. I saw a metallic nature in them based on Fermi level fixed from the tbase3_5.out at the end of the GS SCF calculations. However, the same calculation with VASP showed it to be an insulator agreeing with published re...

error messages in optimisation run.

I am trying to optimise the ions for a 108 atom amorphous system. I am using the input file given in test case 81 in the package. For most of the higher pressures, the code runs smoothly.. with energy converged, but with large forces (> tolmxf 5Ha/Bohr). The stress conditions however seem to show is...
