 IDBA is the basic iterative de Bruijn graph assembler for second-generation sequencing reads.
 IDBA-UD, an extension of IDBA, is designed to utilize paired-end reads to assemble low-depth
 regions and use progressive depth on contigs to reduce errors in high-depth regions. It is a
-generic purpose assembler and epspacially good for single-cell and metagenomic sequencing data.
