Subject: Albany workshop

Dear colleagues,

I have detected some minor typing errors in the draft
I have sent to you. I made the corrections, but perhaps
more important, I have also added an appendix where
is shown, that the complex story of parameter definitions
on the local level is contained in four sets of rather
simple equations.

I understand if some of you feel frustrated when, after
many years of discussion, I put forward a new definition.
Everybody however will agree that we need some extension
of conventions to make things unique, and these should be
easy to understand.

>From my point of view, our decisions concern:

(1)     A convention on the sequential order of x- and
        y-rotations. (I suppose that everybody agrees
        on the z-rotation which should be the first one.)

(2)     A convention on the definition of mean frames
	yielding symmetric basepair step parameters.

(3)     A convention on the definition of basepair mean
        frames, to be used for calculation of local
        basepair step parameters (including the definition
	of intra-basepair parameters).

Thank you very much for your efforts to evaluate my
suggestions in the light of other definitions.


With best regards,

Heinz Sklenar
