How can i plot the current in the resistor? I done with the green arrow "launcher.sym",

name=h1
descr=Annotate 
tclcommand="ngspice::annotate $netlist_dir/bandgap_op.raw op"

but i get an error: "invalid command name ngspice::annotate"

replace command '`ngspice::annotate`' with '`xschem annotate_op`'

When I open xschem appear this "END SKIP RECORD", also when I do netlist... the library is loaded from here (see the figure).... Is this wrong? If I only open the "xschem" nothing appear... I undestood the problem, but i don't know how to solve.... I need to copy "xschemrc" file in the directory where do i have the schematic?

You don't need to use set_paths. Just delete that line.

set_paths

is used if you want to change the library paths while schem is running. in xschemrc which is loaded on startup you don't need to use it. Where did you get an xschemrc with this set_paths function? If xschem tells you there is no such

set_paths

command and if you see the SKIP RECORD lines this means you have an ubuntu xschem installation. so do a

sudo apt purge xschem

remove the

.../share/doc/xschem

and the

.../share/xschem

directories and install xschem from source as explaned here.

this is the results.

Perfect also verify if no /usr/local/share/xschem or /usr/local/share/doc/xschem is existing or any other xschem directory: do a :

find / -xdev  -name xschem -type d

to find any directory named xschem and verify no old stuff is lying around.

everythings seems ok... the Xschem is installed under tools folder (define by me). The same for pdk folder....

I have a suggestion: do not use the super user (root) account for your normal work. Use a normal user account, and use the root account only for maintenance. The directory layout is unfamiliar to me. Are you using a container/docker/something?
