'E' type signals not exported in ocean

Hello,

I'm exporting the signals of a subckt with Ocean, however, some signals are ignored. The three signals in the image bellow market as "E" are ignored. What does "E" stand for? I couldn't find it in the manual (figure 2).

If I double click in the "E" type signals I can see their waveform V(t) being correctly displayed.

And bellow are the exported signals. What are the ".gi"? I don't need them. They are increasing my files size from ~200kB to more than 2MB. I tried saveOption( 'save "allpub")  but the result is always the same as saveOption( 'save "all") .

Here's how I export the signals:

all_signals_v = outputs(?result "tran" ?resultsDir path_psf)

;Loop to get the voltage value of each cell and save in the specified file
for( i 0 length(all_signals_v)-1
    cell_name=nth(i all_signals_v)

    cell_voltage = value(v(nth(i all_signals_v) ?result "tran" ) time_export)
    if( boundp( 'cell_voltage ) && cell_voltage then  ; boundp checks if a symbol is bound (has an assigned value).
        fprintf(symmaryFile "%s %g \n" cell_name cell_voltage)
    )
);for

Thank you.

Regards,

Raphael
