<div dir="ltr"><div><div><div>Dear <span>Li-Chang,<br><br></span></div><span>The number of projections you choose must be in accordance with the number of Wannier functions you consider. In your example, you have chosen 4 orbitals for B (one s and three p) and 6 orbitals for Ca (one s and 5 d), so totally I think you have chosen 10 orbitals. If you get the error message '</span><span><span>too much defined projections</span>', surely you have chosen less Wannier functions than 10 (what is your value for input parameters num_wann or num_bands)? <br>
<br></span></div><span>Hope this helps, best regards,<br><br></span></div><span>Julen<br></span></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Apr 24, 2013 at 5:26 AM, 尹利长 <span dir="ltr"><<a href="mailto:lcyin@imr.ac.cn" target="_blank">lcyin@imr.ac.cn</a>></span> wrote:<br>
