Does function wthrmngr work correctly?

Dear wavelet toolbox users,
I need to find best denoising settings (DWT vs SWT, fixed-form vs penalised threshold, soft vs hard). I got into problem computing thresholds for SWT.
- How can I compute the fiexd form and penalised thresholds for different sigmas?
- Function "wthrmngr" gives different threshold vaues as wavemenu GUI! For example: thfunc=wthrmngr('sw2ddenoLVL','penallo',swc,1.5) does not give the same value as wavemenu GUI choosing "Penalise low". Which is the right one? The issue was pointed out already here. Unfortunatelly no answer.
- Is the mathematical background for penalised threshold for SWT same as for DWT - which is documented here ?
Any prompt respond would be highly apprecated! Thank you in advance.
Nice sunny day on, Maja
