Apply Layer Offset

[Steven Roche]

How can I apply an offset to change where a layer is loaded within neuroglancer? I am using the following code to append the layer: 

def ngLayer(data,res,oo=[0,0,0,0],tt='segmentation'):
    return neuroglancer.LocalVolume(data,volume_type=tt)

Bu when I try to apply something like voxel_offset, I get an error with this code:

def ngLayer2(data,res,oo=[0,0,0,0],tt='segmentation'):
    return neuroglancer.LocalVolume(data,dimensions=res,volume_type=tt, voxel_offset=oo)

How can I move where the layer is added?

Note, the error I receive is: AttributeError: 'list' object has no attribute 'rank'
