<font size="2"><font size="2">Dear Wannier90 users and 

developers:

<br />

<br />    I'm a newbie of QE and Wannier90, I'm studying a paper 

"Thermoelectric of 

single-layered SnSe sheet" (here is the paper's 

link:http://www.ncbi.nlm.nih.gov/pubmed/26367369),

<br />and I want to make the same result as the paper's, e.g. seebeck 

coefficient and conductivity. First I relax the structure, and </font><font size="2"><font size="2">I follow the step in the example 16 of wannier90 

tutorial,

<br /></font>but the result I get is quite different from 

it:</font></font>

<div><img src="/cgi-bin/owmmdir2/openwebmail-viewatt.pl/comparison.png?action=viewattfile&sessionid=n16031320*-session-0.78883308455455&attfile=n16031320%2A-session-0.78883308455455-att1457161290&" />
</div>

<div><font size="2"><font size="2"> Could you please 

tell me which part I should modify ? Here is my input file below, the 

profile  in 

the attachment is the same input 

file,  </font></font>

<div><font size="2"><font size="2">if you want to 

make a test  

you can just download and execute 

it (you have to modify something like pseudo_dir...etc). 

<br />Thank you in 

advance.
