<p style="margin-bottom: 0in;" align="justify"><span style="font-family: Times New Roman, serif; font-size: 12pt;">Hi</span></p>
<p style="margin-bottom: 0in;" align="justify"><span style="font-family: Times New Roman, serif; font-size: 12pt;">I am trying to run ACBN0 calculation for NiO to get the Hubbard parameter. Since Ni has an anti-ferromagnetic structure, in the input file, there should be set two Ni atoms, namely Ni1 and Ni2. They are equivalent except that they have different magnetic moment directions. Unfortunately, ACBN0 gives two different Hubbard parameters for Ni1 and Ni2 (data is attached to this message).</span></p>
<p style="margin-bottom: 0in;" align="justify"><span style="font-size: 12pt;"> <span style="font-family: Times New Roman, serif;">Could you suggest me the solution for this problem?</span></span></p>
<p style="margin-bottom: 0in;" align="justify"> </p>
<p style="margin-bottom: 0in;" align="justify"><span style="font-family: Times New Roman, serif; font-size: 12pt;">Thank in advance,</span></p>
