<p><b>How to know which k points mean which high symmetry point?</b></p>
<p>For this question, page 6 might be helpful to you in the document
at the following link that has a screenshot identifying the Gamma
point for GaAs by looking at the xmgrace band structure plot:</p>

<div dir="ltr">Dear Dr. Rubel,

<div dir="auto">I computed the effective mass of GaAs, but I
did not get the result as mentioned in the article. Moreover,
I did calculation in two ways 1. Just with x lapw1 and x
lapwso 2. By generating kpath L-Gamma-X for 100 points (x
lapw1 -band and x lapso). I found the results are different.
What is the difference between the two calculations? Are they
the same? Do they affect effective mass?</div>

<div dir="auto">I may not understand or read the output results
correctly. So please explain about the output to read. In the
article it is written that 13 k points mean gamma point. How
to know which k points mean which high symmetry point? In the
case of an indirect band gap, VBM is at Gamma and CBM is at X.
How to search for results in the output file in such a case?
Please explain in detail about extracting data from output
files.</div>
