You need (two) END cards here to finish the group specification for the ntr
section. Then the belly group specification begins. They are *not* part of
the same group.

You left out much of your input file...did you expect to have NMR restraints?
The best thing to do is to include a line
DISANG=dummy
right after the "&wt type='END' &end" line. Then make a zero-length file
called dummy, if you have no restraints. (This won't be necessary in the
next release).
In summary, the mdin file should look like:
title
&cntrl
nmropt=1, ibelly=1, ntr=1, ...
&end
&wt .... &end
&wt type='END', &end
DISANG=dummy
title for ntr input
5.0
RES 1 52
END
END
title for belly input
RES 1 1
END
END
..good luck...dac
