 * You can use `--featurecounts_feature_type CDS` in combination with `--featurecoutns_group_type product` but than featureCounts will no longer reflect the biotypes of your RNA. It could be helpful to identify the number of hypothetical proteins.
 * If your execution struggle with Salmon as aligner, change `--alginer` to hisat2.
 * You can skip RSeQC with `--skip_rseqc` since it mainly focus on eukaryotic features like splice junctions, transcription start (TSS) and ending sites (TES)
-* If you aren't interested in the biotypes of your RNA data, you can skip the whole process with `--skip_biotype_qc`
+* `--skip_biotype_qc` in case biotypes of your RNA data are of no interest.
