ScilabDataAnalysisTemplate

This is a template for data analysis with scilab.
It is mainly intended to facilitate use and minimize potential errors by :

  • enforcing a consistent directory structure
    For each novel data analysis problem, the idea is to create a novel directory containing at least

    • WRK: working directory for the data analysis problem
      • DAT: data used as input for analyses
      • RES: results of analyses
      • PRG: scripts and functions for the analyses

  • compiling all functions in PRG when you run main.sce
    This is handy, though you must re-run main each time you modify a function. The compilation is done in InitTRT.sce

  • providing a minimum set of ingredients for time series processing
    • LIB_Signal
      • AmplitudeSpectrum.sci Amplitude spectrum of a signal from fft
      • LowPassButtDouble.sci Low pass filters a signal with a dual-pass second-order Butterworh iir filter
      • fltsflts.sci Applies a filter forward and reverse in time (zero phase shift filtering)
      • gradient.sci One-dimensional gradient of a signal (first central difference)
      • unwrap2pi.sci Unwraps phase by changing jumps greater than pi to their 2*pi complement
    • FourrierAnalysis.sce
      Illustrates the use of the library

Usage

  • (Clone or) download the repository
  • On your computer :
    • Open main.sce with scilab editor (SciNotes)
    • Run the script (press F5, or click the button with a triangle)

Notes :

  • You first need to install Scilab... For OSX users: please go directly to the guidelines provided by the University of Technology of Compiègne (link on scilab's page) and follow thme step by step.
  • Double click on main.sce might not work... depending on your OS.
    Opening files from SciNotes always works (File menu -> open).
  • Do not modify the names and organisation of the directories
    The DAT+PRG+RES structure is expected when initialising in InitTRT.sce
