@User it works this way: load the top level schematic, run the spice simulation, if you give the 'annotate' command the .OP voltages and currents are displayed in the schematic. Now if you descend the hierarchy and give again the 'annotate' command the current schematic will be annotated with results from .raw file of schematic at top hierarchy. This is the reason why for annotate to work correctly you must run a simulation from the top-most schematic level.The 'ngspice_annotate.tcl' script always loads the .raw file of the root schematic.
