Hi. I used this some time ago and it worked beautifully. Today I was not able to run it in my saoimage ds9 7.5 on my mac with Sierra... I guess the versions were not happy with each other I re-installed the package from scratch and by loading the ds9_pvextract.ans and .py scripts in the master directory I was able now to see the pvextractor line in the analysis menu. Then I loaded a cube , drew a line and did both clic and 'x'. The prompt reacts but the slice frame is never produced...

Also, I tried to run in ipython but spectral-cube gives me a long complicated error about a singular matrix...

AH. Had a CDELT4 = 0.0 in the header that was a problem also for spectral_cube. Eliminated that and voila. Thanks anyways!
