Thanks a lot Stephane.
Though I don't get any error on the ocean prompt when I write

monteExpr( "avginew" "-1.0*average(clip(i(\"V6:p\") 1n 1.3n))")

But after monteRun, I still get this error as follows:

Error found by spectre during Monte Carlo analysis `mc1'.
    ERROR (SPECTRE-8003): mc1-003_subckts: Error evaluating ocean
expression
        `avginew=3D-1.0*average(clip(i("V6:p") 1n 1.3n))'.

though I can successfully get average using

plot(-1.0*average(clip(i("V6:p") 1n 1.3n)))

Can you throw some more light on it?
