find and replace multiple net expressions on a schematic

Hi there,

I am trying to perform a "Find & Replace" of multiple netexpressions in Virtuoso Schematic

I invoked Edit->Replace and in the drop down select box chose netexpr and in the text box typed my expression as

[@nwell:%:vnwell]

Strangely virtuoso schematic returns withwarning #1145, claiming no such objects were found. I can clearly see the object on screen.

(I also tried the simpler option of replacing the label, which does a naive replacement of my net expression's label and abandons the expression part of it, thereby reducing it to a static label. This is not what I want.)

Any help is greatly appreciated

Thanks

Raj
