Neper -S error: Failed to parse directory

[Yuanguo1994]

Hello, guys. It's me again. I have problem in using neper S mode to postprocess the simulation result.
I have read through the nper manual, but still feel confused about the S mode. In the book, the command should be like this 'neper -S fepx_res_dir'. 'fepx_res_dir' should be the raw data directory. Does it mean I should type the file path of the raw data for 'fepx_res_dir'? Actually, I have tried, but it failed as follows:

yt2n19@UOS-218102:/mnt/c/Ubuntu-app$ neper -S 2_triaxCSR

Could you please give me some guidance?

This is a path issue, you must provide the precise location of the directory which contains the output. It seems you are in your top-level directory (Ubuntu-app), and to run the command you provided, you must be in the directory directly above 2_triaxCSR. Alternatively, you could provide the path to the 2_triaxCSR in your neper -S command.

Example 1: You are in /home/path/to/examples/ which contains the folder 2_triaxCSR. You can simply run neper -S 2_triaxCSR.

Example 2: You are currently in /home/. You would run neper -S /home/path/to/examples/2_triaxCSR/.
