Reads assembly quality
WebNov 14, 2024 · The statistics of read-to-contig alignments are also calculated to assess assembly quality, including read mapping rate, read splitting rate, and average alignment depth. Read mapping rate indicates the proportion of reads that can be aligned to assembled contigs. A higher read mapping rate suggests better completeness of the … WebWith the increasing affordability and accessibility of genome sequencing data, de novo genome assembly is an important first step to a wide variety of downstream studies and analyses. Therefore, bioinformatics tools that enable the generation of high-quality genome assemblies in a computationally efficient manner are essential.
