WebJan 18, 2024 · Adapter removal. For reads derived from short DNA fragments, the 3' ends may contain portions of the Illumina sequencing adapter. This adapter contamination may prevent the reads from aligning to the reference genome and adversely affect the downstream analysis. If you suspect that your reads may be contaminated with adapters … Web3.trim all reads in front and tail 4.cut adapters. Adapter sequences can be automatically detected, which means you don't have to input the adapter sequences to trim them. 5.correct mismatched base pairs in overlapped regions of paired end reads, if one base is with high quality while the other is with ultra low quality
