NPORT: mismatch between number of noise parameters and number of ports

I am using Cadence IC 6.1.3. I have a problem simulating the specific attached touchstone file using the nport component. After netlisiting, I get the following error *** START error **** ERROR (SPECTRE-10008): "xxx/sqvco8_xcouple.s8p", line 163: Error:Mismatch found between number of noise parameters and number of ports. *** END error******* The netlist generated is shown below *** START netlist *** // Generated for: spectre // Generated on: Apr 7 00:47:49 2011 // Design library name: DraftLib // Design cell name: n8port // Design view name: schematic simulator lang=spectre global 0 include "xxx/allModels.scs" // Library name: DraftLib // Cell name: n8port // View name: schematic PORT1 (p2 0) port r=50 type=dc PORT0 (p1 0) port r=50 type=dc NPORT0 ( p1 0 net18 0 net16 0 net14 0 p2 0 net10 0 net8 0 net6 0) nport \ interp=rational thermalnoise=no datafmt=touchstone \ file="xxx/sqvco8_xcouple.s8p" simulatorOptions options reltol=1e-3 vabstol=1e-6 iabstol=1e-12 temp=27.0 \ tnom=27 scalem=1.0 scale=1.0 gmin=1e-12 rforce=1 maxnotes=5 maxwarns=5 \ digits=5 cols=80 pivrel=1e-3 sensfile="../psf/sens.output" \ dochecklimit=no checklimitdest=psf sp sp ports=[PORT0 PORT1] start=1e4 stop=1e9 lin=1e2 annotate=status modelParameter info what=models where=rawfile element info what=inst where=rawfile outputParameter info what=output where=rawfile designParamVals info what=parameters where=rawfile primitives info what=primitives where=rawfile subckts info what=subckts where=rawfile saveOptions options save=all pwr=all currents=all useprobes=yes \ saveahdlvars=all *** END netlist *** I do not have any noise paramaters in my touch stone file and I cannot figure-out why I am getting this error.
