If I run the command:
shape-it -r mol1.sdf -d mol2.sdf -o mol1-ref-out.sdf -s mol1-ref-score.txt --noRef
The stdout suggest the option to suppress the reference in the output sdf is recognised:
But the reference structure is included and the scores are not mol1-ref-out.sdf.
Note: This only happens when compiled with RDKit, if I use OpenBabel this options works as expected.
