    In computational sciences such as image processing, publishing usually isn't enough to allow other researchers to verify results. Often, supplementary materials such as source code and measurement data are required. Yet most researchers choose not to make their code available because of the extra time required to prepare it. Are such efforts actually worthwhile, though? View full abstract»

  • Automated Capture of Experiment Context for Easier Reproducibility in Computational Research

    Publication Year: 2012 , Page(s): 48 - 56
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (4904 KB) |  | HTML iconHTML  

    Published scientific research that relies on numerical computations is too often not reproducible. For computational research to become consistently and reliably reproducible, the process must become easier to achieve, as part of day-to-day research. A combination of best practices and automated tools can make it easier to create reproducible research. View full abstract»

    Research computing in radiation therapy is transitioning from small-scale computing to large software systems. Accelerator-mounted imaging devices collect multiple images at every treatment fraction, creating datasets of hundreds of images per patient. Compounding this challenge is the fact that software infrastructure upgrades are difficult to manage in academic environments, due to inadequate ex... View full abstract»
