GSP Problem (Unable to Understand what patterns are significant) [SOLVED]

bunnypanda

Hello,

I need a little help in the GSP operator. I managed to run a GSP problem and obtained the following result from IOObject, however, there is nothing In the "GSPSet (GSP)" window.
0.259:      
0.173:    
0.173:    
0.132:    
0.266:    
0.140:    

It seems to me that the GSP has identified a number of statistical significant patterns and the numbers tell you the confidence level of that sequence. However, I cannot understand what patterns they refer to, for example, I expect a result like:

Seq. pattern: (A, B, C): 0.212
Seq. pattern: (<A,B>, <B,C>): 0.195

Please help. I believe that I may overlook some important steps to visualize the result.

Many thanks,
Bunny

The problem that the GSPSet windows only shows the (empty) annotations page is a known bug that has already been fixed internally. It will be included in the next release.
