I don't think so. The "pw2casino" routine simply takes data from QE and <br>
writes it into a CASINO-readable file, if I remember correctly. In doing <br>
that, it computes some additional energy terms and checks that the <br>
re-computed energy matches the one previously computed by QE. The error <br>
message means that this is not happening. Hard to say why without a test.<br>

The amount of RAM does not depend upon the specific PP, as long as the <br>
two PPs are of the same type. There must be either something very very <br>
wrong in the PP conversion, or something else happening. Again, hard to <br>
say more without a test.<br>
