From: Discarding duplicate ditags in LongSAGE analysis may introduce significant error
Predicted versus observed duplicate ditags in a LongSAGE study of pancreatic acinar cells [4]. Predicted ditag counts, two for each observed ditag, were calculated according to equation 3 (see methods for details). (A) All observed ditags are included. (C) Outliers, according to table 4 were removed. Standardized residuals were calculated according to equation 4. The confidence interval at three standard deviations is shown as lines. (B) All observed ditags are included. (D) Outliers, according to table 4 were removed. The recalculated confidence interval at three standard deviations is shown as lines.
