Dear Co-Ordinator,
I am using Avagadro for obtaining the first three lowest energy
conformers of trimethyl phosphine. When I tried to optimise using conformer
search I got 26 structures. I had to optimize one by one to obtain the three
lowest energy conformers. But they are not matching with the one quoted in
literature as the stable conformers at room temperature. Is it that the stable
transformers at room temperature need not be corresponding to the ones wth
lowest energy?
Please suggest me a way to use Avagadro to just how to put constraints on
optimization. Somehow I could not do it ( may be a sample file of any molecule
including the constraints).
Also I request you address the other problem
regards
Raja

Dear Avogadro discussion list members,
For research purposes, I'm looking for a software package that is able
to calculate the size of organic molecules with weights ranging from
200 to 500 g/mole, as either an equivalent spherical diameter, or
dimensions along the 3 axes. Is there a tool within Avogadro that
calculates molecular size ?
Kind regards, Arnout

Avogadro does have a measure tool, which allows you to measure between atoms,
and several features (e.g., the align tool) that allow you to align a molecule
to a particular reference frame.

But your question makes it sound like you want to do this for a large batch of
molecules. If so, I?d suggest you look at writing a little script, e.g., with
Pybel:

Hope that helps,

I would like to use Avogadro as a way to create energy-minimized molecular
conformations for an NMR prediction platform called PERCH.
PERCH will only accept 3D structure files in *.mol or *.mms format.
How can I save the Avogadro-generated 3 structure as a *.mol file?
Thanks

Hi Brent,
Did you try:
File >> Save as >> "mymolecule.mol"?
Best,
Dave

hello,
I am starting to use Avogadro latest version 1.1.0 . I am working with a
cluster system. Is there a way to only display atoms and hide all bonds?
Without manually removing each of them.
Thanks!

Good question. At the moment, no. I see that you're using a @me.com address. If
you'd like this, I can code it up in a few minutes and add it to the nightly
Mac build tonight?
