Hi,
We are using obabel to perform geometry optimizations etc on the
command line, and we are hitting a bug that seems to only present
itself on the Mac. If the input and output formats are the same then
the operation fails, for example,
obabel -icml -ocml --minimize --log --ff UFF
That is using standard in/out, but it also seems to happen when using
files. This works as expected on Linux and Windows, are we diverging
from expected use too much or is this a bug. This is the same in 2.3.2
and master, using 10.6.8 and GCC 4.2.1.
The full output is below, compared with using xyz as the output (we
could of course work around this issue by using different formats).
There is a SMARTS error I just noticed too, but that seems unrelated
to this bug on the Mac.
$ obabel -icml ethane.cml -ocml --minimize --log --ff UFF
