[xcrysden] Problems of Xcrysden with pwscf files

[Elie Albert Moujaes]

Dear all,

after solving all the problems in initiating XCRYSDEN, i have got a small 
problem now in opening PWSCF files. The input and output files open but they 
ask for the dimensionality and I click OK, I get an error message:

/espresso-4.2/XCrySDen-1.4.1../scripts/pwo2xsf.sh :line 87:bc :command not 
found 

and underneath I get:

/espresso-4.2/XCrySDen-1.4.1../scripts/pwo2xsf.sh :line 88:test :-eq: unary 
operator expected

Can someone explain to me what is the problem please.

Thank you in advance

Regards
