    In WIEN2k_14/SRC_BerryPI/BerryPI/Installation/readme.org, there
    should be:<br>
    <br>
    * Dependencies<br>
      - WIEN2k (tested against 13.1 Release 25 June 2013) <- <span
      id="yui_3_16_0_ym19_1_1504924766400_5561">wien2k14 instead of 13.1
      should be okay here</span><br>
      - WIEN2WANNIER (tested against v1.0-beta2)<br>
      - Python (tested against 2.7.4)<br>
      - NumPy (tested against 1.6.2)<br>
    <br>
    As the readme.org file shows, yes, WIEN2WANNIER is needed for
    BerryPI.  I believe WIEN2WANNIER should already be compiled from
    when you installed WIEN2k_14.  If not, you should be able to compile
    the program in WIEN2k_14/SRC_w2w.<br>
    <br>
    Though, if it were me doing a BerryPI calculation, I would use
    WIEN2k 17.1 as Oleg mentioned.  That is because 17.1 is an important
    update that removed bugs from WIEN2k that were found in the older
    versions [ <a class="moz-txt-link-freetext" href="http://susi.theochem.tuwien.ac.at/reg_user/updates/">http://susi.theochem.tuwien.ac.at/reg_user/updates/</a> ].  <span
      id="yui_3_16_0_ym19_1_1504924766400_5561"></span><br>
    <br>
    The WIEN2WANNIER has also evolved as mentioned by Oleg.  However,
    the WIEN2WANNIER and BerryPI packages included in WIEN2k 17.1 might
    still be older versions that are slightly broken and incompatible
    with each other [

    ].  <br>
    <br>
    So I would replace the WIEN2WANNIER and BerryPI packages in WIEN2k
    17.1 or use instead the latest github versions:<br>
