Hi Sara,
Assuming you have a 32 channel wide uv dataset, and you wanted to make 2 cubes from it, you would run invert twice. To image the first 16 channels you would specify line as "line=chan,16,1" and to image the second 16 channels you would specify line as "line=chan,16,17".
The line spec "line=ch,1,1,16,1" would produce a one-plane cube where 16 channels are averaged together, which is not what you want.
The line spec "line=chan,16,1" would produce a 16-plane cube, where each plane is one channel of the uv data, which is what you want.
