Documentation and software support

SFRplus can be run either through the highly-interactive Rescharts interface or as a batch-capable fixed module. The key documentation for getting started is Using SFRplus Part 1, found in the SFRplus section of the Documentation page. We recommend framing the chart with a small amount of white space above and below the top and bottom bars. Badly-framed charts can be analyzed with SFR using manual ROI selection.
