Maybe I found the reason: 

! Obtain the Modal Solution
/solu
antype, MODAL
modopt, LANB,12 ! Block Lanczos
solve
finish

! Perform the modal selection and expansion
/solu
antype, MODAL, RESTART
mxpand,,,,yes,0.1,, MODM ! Mode selection is based on the modal effective mass, and element
! results are requested
modseloption,no, no,yes, no,no,no ! Only direction X is selected, a minimum of 90% of the total
! mass is requested in this direction
solve
finish

I need to perfom a pre-modal simulation and after I can apply my filters. 

Is it the only solution right? 

Thank youÂ
