SASBDB, a repository for biological small-angle scattering data.
Bottom Line: Due to recent advances in instrumentation and computational methods, the quantity of experimental scattering data and subsequent publications is increasing dramatically.The need for a global repository allowing investigators to locate and access experimental scattering data and associated models was recently emphasized by the wwPDB small-angle scattering task force (SAStf).At present the quality of deposited experimental data and the accuracy of models are manually curated, with future plans to integrate automated systems as the database expands.

Mentions: Experimental solution scattering data are presented as log10I(s) versus s (Figure 1E) where I(s) is the intensity and s is the modulus of the scattering vector (in nm−1). Due to experimental errors a small number of intensities may be negative, these data points are shown as absolute values in red. To facilitate the comparison of different data plots the following convention is observed: one order of magnitude on the I(s) axis has the same length (in pixels) as one inverse nanometer on the s axis. Plots of experimental data that contain angles higher than 6 nm−1 are displayed with a horizontal scroll bar. This is a convenient way of representing wide-angle X-ray scattering (WAXS) data.
