Description
Contents
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:
2. nrec is based on standard technology for robustness and enduring usability
- hardware independence:
standard PC
standard graphics card
comedi data acquisition library supports a lot of standard cards/boards/boxes
- 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
- graphics primitives:
- circle
- rectangle
- arrow
3D dotfield (stereo-mode: none, anaglyph, quad-buffer)
circular checkerboard, also in parts, with flickering and radial and tangential movement
eyetracker calibration, fixation control, online data visualization
- the option to make a primitive a visual target
- controllers that make the primitives move and jump and that handle digital in- or outputs
- freely configurable digital channels for respone buttons, reward systems, LEDs etc.
- experiment control by strategy based parameter setting
luminance correction by using a freely definable alpha mask loadable from a simple file
