manual for the nrec_analyse Matlab project

1. What is nrec_analyse?

nrec_analyse is a Matlab project to read and analyse nrec data that has been stored into hdf5-files.

2. System Requirements

You need Matlab R2009b to run nrec_analyse.

3. What do the columns of the TrialList Matrix mean?

In the columns the following values are stored trial by trial:

  1. Trial number starting with 1 (Matlab-style).
  2. Number of samples in the eyeposition data matrices EyeX, EyeY.
  3. Pool number as specified by the parameters in the description file for the given paradigm type (see below).
  4. 1 if valid, else 0. Trials usually are invalid in case of a fixation failure or a missing or invalid answer.
  5. Level value of the currently active strategy. 0 if no strategy is used.
  6. 1 if the given answer was correct, 0 otherwise.
  7. The value of the given answer. Usually 2, 4, 8 or 16 in case of 4 available answer buttons.
  8. The time at which the answer was given relative to trial starttime.
  9. Starttime relative to starttime of first trial.
  10. Stoptime relative to starttime of first trial.
  11. and following can be specified by the numberOfExtraColumns and nameOfExtraColumnN parameters in the description file for the given paradigm type (see below).

4. How can i define the pool number that is stored into the TrialList matrix that contains the information for each of the trials?

5. How can i configure it to read certain values into the TrialList matrix that contains the information for each of the trials?
