psychopy_ext.fmri.Analysis.ds2evds

Analysis.ds2evds(ds, dur=2)[source]

Converts a dataset to an event-related dataset.

Args:

ds

Kwargs:
  • offset (int, default: 2)

    How much labels should be shifted due to the hemodynamic lag. A good practice is to first plot data to see where the peaks are. Default is 2 as a typical TR is between 2 and 3 secs and the lag is around 6 seconds.

  • dur (int, default: 2)

    How many timepoints per condition. You may want to use a couple because the peak response may occupy more than a single timepoint (thus the default is 2).
