Question regarding dir_data options in demo.sh, and image database layout

[drcdr]

I noticed that there are several different --dir_data arguments in the demo.sh file:

../../datasetx4
../../datasetx3
../../datasetx2

What do these refer to? I have a single dataset set up as shown, and things seem to be running OK. But, the EDSR_paper template seems to be taking a long time; understandably, but I was wondering if I should be using a different database in some way.

<dirname>

    |- B100
        |- HR
        |- LR_bicubic: under this, X2, X3, X4
    |- Set5
