Liberate can't read the cell netlist

Hello,

I am trying to characterize a cell using LIBERATE23.11.221. However when I run my .tcl script it tells me that it failed to open the file for read.

However, when I check the access permission, it is supposed to be readable ....

The cell netlist has been saved using the "save as" option in the netlist generated with ADE Explorer

Here are the lines in my TCL file that import my model and read the netlist (It is based on this post https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/42649/liberate-characterization---errors-with-encrypted-pdk-model-file and the documentation on LIBERATE)

set_var extsim_model_include /home/mathieu/Cadence_Custom/Sim/Corners/corners.scs
read_spice -format spectre SRAMCell_gnd.scs

Do you have any suggestion on how to solve that ?

UPDATE : I indicated the full path to the file and Liberate can read it now. However it does not handle encrypted parts in included files....

I am usign an encrypted PDK Model file and I get this error

Error: Statement is not in Spectre format. Use `simulator lang=spice' to introduce spice language sections.

I followed this post https://community.cadence.com/cadence_technology_forums/f/custom-ic-design/42649/liberate-characterization---errors-with-encrypted-pdk-model-file

but it does not seem to work here

Do you have any suggestion ?

Thanks in advance

UPDATE 2:

The saved netlist has 2 include lines that made Liberate fails.

include "importNetlist.scs"
include "/home/mathieu/Cadence_Custom/Sim/Corners/corners.scs"

I commented them and I do not have the errors anymore
