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
- dotfield (RDK)
- text
- arrow
- movie (avi)
- image (png)
- square plaids
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
