Nowadays, biclustering problem is still an intractable problem. But in time series expression data, the clusters can be limited those with contiguous columns. This restriction makes biclustering problem to be tractable problem. However existing contiguous column biclustering algorithm can only find the biclusters which have the same value for each column in biclusters without error tolerance. This characteristic leads the algorithm to overlook some patterns in its clustering process. We propose a suffix tree based algorithm that allows biclusters to have inconsistencies in at most k contiguous column. This can reveals previously undiscoverable biclusters. Our algorithm still has tractable run time with this additional feature.
