Further to my last message, I noticed that there was a directory problem (asap didn't seem to be able to cope with a space in a directory name), so I removed the space (note this wasn't a problem in the old version of asap on my laptop). When I fix this I then get the following error message. Note that reading in the files is taking an absolute age. Again much longer then before??

This is broken in the release, but will be fixed in the next release.

# Separate the on and off-source scans
ref = scaled.get_scan('*[ew]')
src = scaled.get_scan('*[^ew]')

Please use this instead

ssel = selector()
ssel.set_query("SRCTYPE==0")
scaled.set_selection(ssel)
src = scaled.copy()
ssel.set_query("SRCTYPE==1")
scaled.set_selection(ssel)
ref = scaled.copy()
scaled.set_selection()

I think this (easier) version might also work.

q = scaled.auto_quotient(preserve=False)
