A demonstration of how a \textit{p-v} slice was extracted along a path tracing the extinction feature, using the software visualization package Glue. First, using the “link data” function, we linked the Galactic latitude and longitude from the Spitzer image (upper left image) with the Galactic latitude and longitude from the GRS(upper right image)  or ThrUMMS fits cubes. cubes (upper right image).  Next, yellow circular regions were created along the extinction feature in the \textit{Spitzer} image, marking the path along which the slice will be extracted. Since the data products are "linked", Glue automatically overlays the same yellow regions on the GRS(upper right)  or ThrUMMS data cube. cube (upper right image).  Then, using the "slice extractor" tool, we trace a path through the centroids of the yellow regions in the CO fits cube, effectively creating a customized \textit{p-v} for slice along  the filament extinction feature  (bottom image).
