How to return PSF folder used by the current VIVA by skill

Hi All

I am writing a script for saving images with predefined .grf setup for the results which is used in the VIVA.

I am kind of blocked at the first step to retrieve the psf folder path which is used by VIVA, (which is high-lighted in the screenshot below).

Especially, psf folder is from a specified corner run like the "…/Interactrive.764/1/tran/psf"

I need this value for the "resultsDir" argument in awvLoadWindow() function.

Many thanks in advance.

Best Regards

Yi
