[Pw_forum] error using plotrho.x

[Hande Ustunel]

Hi,

The message below was posted a little while back and the reply was related
to redirection issues. However, I'm running into an identical problem in
espresso-3.0 and I think it might be related to negative numbers in the
charge density. When I use a preprocessed file that has negative numbers,
plotrho.x fails with the identical message as given in the previous
post. When I change all those numbers to positive and use the same input
with redirection and everything being the same, it works. With my very
limited fortran knowledge I couldn't see anything in the code that would
fail for negative numbers save the logarithmic option but that seems to be
checking for negative numbers already. Has negative numbers ever worked for
anyone in the past?

Thank you very much in advance for any help.
Best wishes,
Hande
