[Wannier] Error in the wannierization

[sblanco]

Dear colleagues,
I am performing a Wannierization of PrBa2Cu3O7 compound.
Carrying out a downfolding to the planar oxygen and Cu and leaving out 
the oxygen on the chain gives no error messages.
Nevertheless, trying to do the downfolding including the Pr atom, gives 
the following error message after the x w2w line:

-bash-4.2$ x w2w -scratch

Can anyone give me a hint about how to solve this problem?
