Motivation: Linking experimental data to mathematical modelsin biology is impeded by the lack of suitable software to manageand transform data. Model calibration would be facilitated andmodels would increase in value were it possible to preservelinks to training data along with a record of all normalization,scaling, and fusion routines used to assemble the training datafrom primary results.
Results: We describe the implementation of DataRail, an opensource MATLAB-based toolbox that stores experimental data inflexible multi-dimensional arrays, transforms arrays so as tomaximize information content, and then constructs models usinginternal or external tools. Data integrity is maintained viaa containment hierarchy for arrays, imposition of a metadatastandard based on a newly proposed MIDAS format, assignmentof semantically typed universal identifiers, and implementationof a procedure for storing the history of all transformationswith the array. We illustrate the utility of DataRail by processinga newly collected set of 22 000 measurements of protein activitiesobtained from cytokine-stimulated primary and transformed humanliver cells.
