Are you using spice-sdb? If so, take a look at the symbol file for the opamp itself. Since 10.14.2003, spice-sdb only puts pins into the netlist if they have a pinseq attribute attached to them. The pinseq attribute should specify which order the pins appear in the pin list on the SPICE card. (Note that I did this because you need to be careful about the pin ordering on the SPICE card since .model and .subckt files list the connecting pins in a particular order. Sometimes the pinnumber and the pinseq are different for a part.) To set the pinseq attribute, you need to select the symbol, do "hierarchy -> down", and then edit the symbol's pins in the symbol editor. Don't forget to save the symbol before leaving the symbol editor. Finally, you may need to delete and reload the symbol in gschem before you can netlist it properly. Stuart
