Day 25


Preprocessed data for each project now up at

There are .tar archives, and unpacked archives so you can fetch images for any give subject or run.

These kindly provided by Russ Poldrack and the folks at the OpenFMRI project.

The processing applied to the scans is:

  • motion correction (coregistration in time to partially correct for movement during the run and between runs);
  • high-pass filtering in time (to remove low frequency drifts / noise);
  • registration to a standard anatomical template (the MNI template).

Using these images, you can estimate the location of a given voxel coordinate in a standard brain millimeter space, using the image affine: Finding the location of a voxel coordinate.
