Subject: About AIM analysis in Gaussian

Dear CCL members
I am interesting in Atom in Molecules (AIM) analysis. I know that G98
had the AIM keyword, nevertheless G03 do not have it. Are there any
technical problem with the AIM code in G98?  Why AIM were removed in
GO3?
Thanks 
Rachel

below is recent correspondence with technical support at Gaussian re:
aim population analysis. I understand Morphy & AIM2000 to be robust aim
tools, good luck, ben....

   Dr. Sattelle,

    I see the problem now.  It is a case where G03 is removing nearly
linearly dependent functions from the basis set, which generally
stabilizes the SCF and post-SCF calculations with little or no loss of
accuracy, but AIM does not know how to handle it and is trying to use
the full NBasis**2 array.

    We have deprecated AIM so it will likely be a long time before a fix
is worked out but you can force G03 to turn off the projection of basis
functions by adding IOP(3/32=2) to the route.
