  A.2 Open Image Files This function looks for x-ray images (.tif) in directory ‘dname’ and creates a movie of I(q) versus q and saves the corresponding 3D matrix. ‘TempA’ and ‘TempB’ are the slope and y-intercept of the ramp temperature profile, respectively. Variables ‘timeA’ and ‘timeB’ are the slope and y-intercept of the time dependence on the frame number. ‘IC1A’ and ‘IC1B’ are the slope and y-intercept of the IC1 value (prior to sample) dependence on the frame number. It load background matrices ‘B’ which should be double-format and corrected for IC1 and any difference for acquisition time. This function calls radialintegrationBNL A.4 Lorentz Correction This function creates and saves the Lorentz-corrected intensity matrix calculated the intensity matrix created in A.2. It also saves each frame as a separate ascii file for crystallinity uation in Origin or other software.
