DthData Armstrong Time-History Software Utility
(DRC-012-024)
Overview
<p>Processing and plotting large amounts of data can be time consuming and expensive, particularly for data that specify time-varying values, so-called time history data. DthData--along with QuickPlot and DthDiff--helps manage several key operations for time history data, enable comparison of the time history files, and efficiently plot gigabytes to terabytes of data.</p><p>A standalone command-line-driven utility program written in ANSI-C, DthData is designed to extract selected signals and time segments from input files and write the selected data to output files. Other capabilities include converting file formats, merging data from multiple input files, time skewing, interpolating to common output frame times, renaming signals, and generating calculated output signals as functions of the input signals. The utility also converts time history files from a compressed format to any format suitable for displaying or plotting, including MATLAB&reg; or Microsoft Excel&reg; formats.
