a Contig coverage versus GC content. Each dot represents a single contig of >1000 bp. Contig coverage was estimated using CLC Genomics Workbench by mapping assembled contigs with Illumina reads that shared 96 % similarity over 95 % sequence red length. Green color dots represent contig having single copy gene/s that have taxonomic affiliation with cyanobacteria. b Principle component analysis of the tetranucleotide frequencies of assembled contigs fragmented to 1,000 bp. Green color dots represent contigs that have affiliation with cyanobacteria, binned using method in (a). All binned contigs have at least 50 % of their open reading frames annotated as being affiliated with cyanobacteria based on best BLAST hits
