Hi Jimmy,
I have all the PLS generated files (I assume you didn't need the raw test data).  It would be wonderful if you can see what I am doing wrong with running the seed analysis.  Included are the session, result, and datamat files.  also the multivoxel extraction and cluster reports.  The cluster report So you can get the files from.

In order to run Behavior PLS (Seed PLS uses Behavior PLS), you will need at least 3 subjects.

You can find this from:

under Figure 17

You can also find this from:

Q:	I got "divide by zero" error when I tried to run Behavior PLS
analysis, while there is no error when I ran task PLS.

A: There are two reasons that could bring you into this trouble:

1. You must have at least 3 subjects to do the behavior PLS.

2. Values should not be all the same for behavior data. Even
if they are really all the same, you must add (or minus) a
slight difference (e.g. 1/1000) to make it work.
