A New Thymidine kinase Research Dash Board Gadget

The integration optimization module, in conjunction with image pre-processing and analysis modules, has been implemented in the program IOTA, which is distributed as part of the cctbx.xfel package (http://cci.lbl.gov/xfel) under an open-source license.

This flash X-ray imaging (FXI) concept has been used to reconstruct two-dimensional projections of mimivirus (Seibert et?al., 2011 ?), whole cells (van?der Schot et?al., 2015 ?), cell organelles (Hantke et?al., 2014 ?) and soot particles (Loh et?al., 2012 ?). More recent advances include the characterization of the three-dimensional structure of silver particles (Barke et?al., 2015 ?) and even a full three-dimensional reconstruction of mimivirus (Ekeberg et?al., 2015 ?). In a typical FXI experiment, a stream of biological particles is injected into selleck chemical the focus of a pulsed X-ray source. Far-field diffraction data are collected downstream of the interaction region. A more detailed description of the experimental setup, using an aerosol particle injector, has been given for example by Hantke et?al. (2014 ?). Currently, a considerable amount of time during FXI experiments is spent on alignment and optimization of the X-ray source, background reduction and finding the intersection between the particle stream and the X-ray beam. These tasks get increasingly harder as we move towards harder X-rays (>2?keV) in a smaller focus (
