DNAA is the DNA analysis package, for analyzing next-generation post-alignment whole genome resequencing data. Specifically, DNAA is able to find structural variation, SNP and indel variants, as well as evaluating the mapping and data quality.
Python tool to evaluate the quality of high-throughput sequencing data
...The analysis contains the sequencing quality along the reads, the mapping quality distribution, the coverage of the defined region, the overall quality at each nucleotide position, and the distribution of the coverage as a function of the GC content in the reference genome. The results provided by this program can help to distinguish between sequence variation and sequencing errors.
