Dear Aguang Dai,

The estabished way to analyse the symmetry properties of a data set is 
through eigenvector analysis  (see: P Dube, P Tavares, R Lurz, and M van 
Heel, Bacteriophage SPP1 portal protein: a DNA pump with 13-fold 
symmetry, EMBO J. 12 (1993) 1303-1309.) Further details in the Symmetry 
and MSA  manuals/papers on: 
http://www.single-particles.org/methodology.html.

Hope this helps,

Marin van Heel

I receive many emails per day and, although I try, there is no guarantee that I will actually read each incoming email. Moreover, our Spam filters can be strikt and sometimes make legitimate emails disappear (try the gmail accounts, alternatively)
