I have been using VMD to try to measure h-bonds in a molecule with the
following script:

#Measure h-bond distance

set reference_sel [atomselect 0 "backbone"]
set cutoff 0
set angle 0
measure hbonds cutoff angle $reference_sel

But I am receiving the following errors (it does not seem to matter qwhich
value for cutoff or angle I chose)

atomselect1
0
0
expected floating-point number but go "cutoff"

Has anyone seen this before, and how might I go about fixing the problem?

Thanks,
