A Web Interface Based on the JINR Cloud Infrastructure for Fitting Experimental Small-Angle Scattering Data Using the Tools of the ROOT Package

Abstract

Obtaining structural information about organic nanoobjects based on the analysis of small-angle neutron and X-ray scattering data is based on fitting experimental data with multi-parametric theoretical functions reflecting model representations of the objects under study. To solve such problems, the FITTER_WEB web application has been developed, based on the new tools of the ROOT package and deployed in the JINR cloud infrastructure. The user is given full control over the citation process, as well as the ability to use the built-in ROOT mechanisms to parallelize this process. The paper describes the structure of the FITTER_WEB web application and the software tools used for its development. The results of using FITTER_WEB to analyze small-angle neutron scattering data on a sample of a poly-dispersed population of phospholipid-based vesicles in heavy water are demonstrated.
