LVDS on Stratix II GX... which pins?

I tried to select as data and clock input of a LVDS transmitter the pins corresponding to the jacks (J26... J49) or to the 20-pin debug header... but i can't fit the design in device because of Quartus II error messages (example: the pin R4 does not support I/O standard LVDS for tx_out).

How can I select the pins on Quartus?

(My device is ESP2SGX90EF1152C3)

    My design about LVDS is based on stratix 2's device EP2S180F1020C5N ,as I have known ,the LVDS pins is on my device are only support on the row bank ,and the transmitted pins must be "TX" pins ,and the receiver pins must be "RX "pins , I think your question is more or less the same as what I have said , you'd better refer your handbook and ensure these.
