Theory

Recently, we have developed an improved version of AutoStructure - AS-DP. The new feature of AS-DP is using DP scores from RPF software to select models generated in AutoStructure’s iterative cycles. Only the top models with highest DP scores and lowest target function (CYANA) or conformational energy (XPLOR) values are selected for iterative AutoStructure NOE analysis. Using a DP filter for model selection improves the accuracy of the selected intermediate structures for iterative NOE analysis and therefore improves the accuracy of NOESY crosspeak assignments and final models. AS-DP has been successfully assessed in the first CASD-NMR workshop [1] in May 2009.

Using AS-DP

A new version of AutoStructure featuring the AS-DP capability is due to be released in 2010.
