[求助] 利用wannier90计算能带报错已有1人参与

我最近在重复Quantum Spin Hall Effect and Tunable Spin Transport in AsGraphane这个工作。尝试利用wannier90计算能带，结果出现如下错误，麻烦有了解的亲们帮忙解答下，多谢多谢！

wannier.win文件内容如下：

【答案】应助回帖

您好，关于您的问题报错信息说是您定义的投影子的数量（Fewer projections defined than the number of Wannier functions requested），您的num_wann = 84，然后初始投影子As : px;py;pz，显然不符合规则，应该是你定义的初始投影子数量与WF数量一致，如果想解决的话，手册中提到一个捷径设置成Begin Projections
random
As：px；py；pz
End Projections，希望对您所帮助
