Jimmy, thank you so much for answering my questions.  I have a major meeting tomorrow, hence the flurry of activity.

I am still struggling with the seed analysis, so let me tell you what I have done and show you the error message I get:

Prior to doing the Behavior (seed) analysis, I did Mean-Centered (generated session files and ST Datamat).
Then I used Cluster Report to find coordinates of the voxels that were significant (n=3).  3 rows corresponding to the 3 voxel addresses, where each row was in X, Y, Z format.  Then I generated a text file of these coordinates in the proper format: one row = one coordinate set ([x,y,z]).  There were three rows corresponding to the 3 voxels indicated by the cluster report.

After that I generated Multivoxel Exraction where I then inputed the text file of the coordinates and generated th Prefix_ERfMRIVoxelData .

Seed (Behavior PLS analysis)
Next I did Run analysis-->loaded the appropriate session file-->Behavior--> Loaded the Prefix_fMRIvoxeldata.txt  file.  Of the 24 Behaviors, I removed columns with 0 across the rows (Behaviors 1, 9 and 17 were removed). Ran the analysis.  The progress bar pops up but gets stuck at  around 70%.

I keep getting the same error:
