Dear All 
I would like to ask what exactly is "MEASURE_GREEN" in worm, which is untested and should not be used.  Is it <b_j^dag b_i> or some version of thermal green function?

yes

If the latter, is there a way to measure correlations "bdag:b". I think that MEASURE_CORRELATIONS[Name]="bdag:b" gets ignored (no relevant output is found).

Indeed, only diagonal correlations can be measured. You need to wait for the next release to measure the Green's function.

In the other hand, MEASURE_CORRELATIONS[Name]="n:n" works fine.
 

Correct
