I have a query about comparing my calculation using the WIEN2K code with<br>
experimental data. We are doing our calculations at absolute temperature<br>
and the experimentalist is doing his measurement at room temperature or<br>
above. Then how I compare my calculations with the experimental,.<br>

The difference is often ignored, in particular if the accuracy limitations of the XC-functional are comparable to the difference between calculation and experiment.<br>
<br>
An example of a more systematic investigation of the difference between DFT (PBE) and experiment for some properties can be found here (<a href="http://dx.doi.org/10.1080/10408436.2013.772503" rel="noreferrer" target="_blank">http://dx.doi.org/10.1080/10408436.2013.772503</a> -- open access, see in particular sec. 2.2 and sec. 3).<br>
