Abstract: QtClassify is a GUI that helps classify emission lines found in integral field spectroscopic data. The main idea is to take each detected line and guess what line it could be (and thus the redshift of the object). You would expect to see other lines that might not have been detected but are visible in the cube if you know where to look, which is why parts of the spectrum are shown where other lines are expected. In addition to that, monochromatic layers of the datacube are displayed, making it easy to spot additional emission lines. As input you need a datacube as well as a catalogue with emission lines and a signal-to-noise cube.
