Change output shape

[AromaticJ]

In the data layer, layer output is list as below:
data -> data 32 3 480 640 (29491200)
data -> label 32 8 120 160 (4915200)
data -> type 32 1 60 80 (153600)

I know the shape of "type" is depended on "catalog_resolution"
But I can't find out where shape of "label" is depended.
If I want to change the output shape of binary-mask, I should change shape of "label" firstly, how can I change "data -> label 32 8 120 160 (4915200)" to "data -> label 32 8 240 320 (4915200)"?
