  1. A web browser should open the following shockwave (swf) movies:
    1. SLFII;
    2. Walker’s Area 46 to CB Ventral via CB Dorsal;
    3. PS Ventral Bank to PS Dorsal Bank;
    4. SLFIII;
    5. AF Frontal to Temporal;
    6. Frontal ROIs (SLFII and AF) to combined SLFII-Parietal and AF-Temporal;
    7. SP Motor Cases 24-29 to putamen;
    8. Fornix_MMB_to_Fimbria;
    9. UF_Frontal_to_Temporal;
    10. FOF_Frontal_to_PO;
  2. Data for evaluation, testing and validation are as follows. Please note images, computed fibers and edited fibers are formatted for use in MRIStudio – see http://www.mristudio.org; the fibers have cost per length appended at the end of the standard file. Low resolution data is also available but recommend using DiffeoMap in MRIStudio to resample the data.
