Composing complex EXAFS problems with severe information constraints

Abstract
In recent work, a model for the structural environment of Hg bound to a catalytic DNA sensor was proposed on the basis of EXAFS data analysis. Although severely constrained by limited data quality and scant supporting structural data, a compelling structural model was found which agreed with a similar but less detailed model proposed on the basis on NMR data. I discuss in detail the successes and limitations of the analytical strategy that were implemented in the earlier work. I then speculate on future software requirements needed to make this and similarly complex analytical strategies more available to the wider audience of EXAFS practitioners.
