Following the hint of Anna (use the python file) I have success to
start the script.

But I have some error.
More probably I insert wrong values.

Infact the script ask me the
"high resolution panchromatic image" . I insert the B8 from landsat8
that is the high resolution image.
after the script ask for the "Low resolution Multispectral images".
Here I need to insert the three images : B4,B3 and B2 of landsat8.
But I'm not sure how to insert them in a combo-list so I click three
time in this sequence: B4 B3 B2" and see they are added one after the

I hope this was the correct sequence because AFAIK in the L8 the red
channel is the B4, green=B3 and blue=B2

However after that insert I click on execute and the plugin report this error.

So I understand I wrong insert the values.
But I don't understand how the script like to have the values inserted.

Any hint ?
