• Eomys / SciDataTool

  SciDataTool is an open-source Python package for scientific data handling. The objective is to provide a user-friendly, unified, flexible module to postprocess any kind of signal. It is meant to be used by researchers, R&D engineers and teachers in any scientific area. This package allows to efficiently store data fields in the time/space or in the frequency domain, to easily perform Fourier Transforms, to extract slices, to convert units, to compare several fields, etc. It therefore leads to simplified plot commands.
