Dear all,
<div><br></div>
<div>I find that even the latest user_guide 3.0.0 doesn’t have a
description about the format of seedname_tb.dat. The format of
seedname_tb.dat is similar to the seedname_hr.dat but I found
that several lines of hamiltonian matrix element have
different format. For example,</div>
<div><br></div>
<div>
<div>normal format</div>
<div><br></div>
<div>band_n band_m Re(H_{nm}) Im(H_{nm})</div>
