Pair distance distribution vs electron density distribution

#1 Post by Ciner » 2012.01.21 18:12

Hi, I'm Caner,
I'm using a laboratory type swaxs system. I would like to ask you some question about SAXS analysis. I'll be glad if you help me about this subject.

I am investigating the relation between pair distance distribution and electron density distribution. I can calculate pair distance distribution with Gnom and I would like to transform that to electron density distribution. Can we use any software for this transform, or can we define any simple equation between these two distribution?

Hi Caner,

the ATSAS package does not have any tools for you to do this, however, Jan Skov Pedersen has an approach in a program called wsDens which will generate a radial-density distribution from the output of WIFT (and in principle GNOM, but I have found that to be tricky).

These packages form part of something called SUPERSAXS but I don't think it is officially released.

Hope it helps!
