A. Expression value calculated is a log value, which might be smaller than 0 (See Methods). This column shows the median expression of all pseudogenes in the tissue of interest.
B. This column counts the number of pseudogenes which has the highest expression in the tissue of interest no matter how much this highest expression should be.
C. This column is similar to the previous column except the highest expression for a pseudogenes should be above the criterion of 0.2. This value indicates a presence of expression by manually checking the correlation between EST data and exon-array data on UCSC genome browser.
