Reads trim
WebAn additional option within Adapter Stripping is Trim reads first. Trim reads first controls the Order of Operations for Trimming and Stripping. For example, if reads were 3' barcoded such that the read was miRNA-Barcode-Adapter, setting Trim reads first to false would allow stripping of the adapter, followed by removal of the barcoded portion.

WebAug 30, 2024 · It is best to trim off any low quality bases at the ends of reads to ensure the best alignment to the reference. Usually a quality score of <25 is considered as a “poor” quality score. Once the adaptor remnants and low quality ends have been trimmed, some reads may end up being very short (i.e. <20 bases).
