[Ifeffit] feff6L and path finder limit

Hi all,

the recent messages on error messages written by the feff6L module of 
artemis prompted me to pose the following question here. Since the 
very first trials with the program, last year, every time I run feff 
using a feff.inp file derived from a structural model that includes 
the metal ion and the few amino acids that would act as ligands to 
it, I get error messages of the type I am including here. Is there 
something wrong or is everything Ok and I should disregard the 
messages?

Regards

Stefano
