[Wannier] Question on skip_B1_tests variable

Dear Carissa,

In Wannier90 2.1, the skip_b1_tests input variable is indeed 
implemented. Can you double-check in the Wannier output file that this 
is the version you are running? ABINIT can be sneaky about downloading / 
installing its "fallback" Wannier90 version during the install.

It's also worth noting that with Wannier90 2.1, you should no longer 
need the 'skip_b1_tests' input variable. Instead, you can let Z2Pack 
write the 'nnkpts' block, which explicitly specifies the overlaps to be 
computed. There relevant documentation can be found here 

Best regards,
