With the emergence of large-scale sequencing platforms since 2005, there has been a great revolution regarding methods for decoding DNA sequences, which have also affected quantitative and qualitative gene expression analyses through the RNA-Sequencing technique. However, issues related to the amount of data required for the analyses have been considered because they affect the reliability of the experiments. Thus, RNA depletion during sample preparation may influence the results. Moreover, because data produced by these platforms show variations in quality, quality filters are often used to remove sequences likely to contain errors to increase the accuracy of the results. However, when reads of quality filters are removed, the expression profile in RNA-Seq experiments may be influenced.
