Description

1. nrec is a software package for stimulation, data acquisition and experiment control

Originally it was designed to be used in cognitive brain research, but it is made to be as generally applicable as possible:


  • acquisition_stimulation.png


2. nrec is based on standard technology for robustness and enduring usability

  • hardware independence:
  • software standards:
    • it runs on a standard debian linux

    • it is developed in standard C++

    • parameter files format: standard XML

    • data storage files format: standard hdf5, Matlab readable

    • graphics primitives are built using the standard OpenGL library


3. Current features
