[…] assembly of genomes is marked by three algorithms: short sequence assembly by progressive k-mer search and 3′ read extension (ssake) , verified consensus assembly by k-mer extension (vcake) and quality-value-guided short read assembler (qsra) where each algorithm is an extension of the previous algorithm., ssake proposed for assembly of genomes that were smaller is size (about 30 kb […]

[…] are the following: [genbank:jk523124] to [genbank:jk525007]., we evaluated several assemblers for the de novo assembly of the e. fischeriana root transcriptome, including oases [], velvet [], qsra [], euler-sr [], edena [] and soapdenovo []. preliminary assembled contigs by each tool were blasted against ncbi non-redundant protein database. we found that oases (velvet version 1.0.12 […]

[…] it is also affected by the complexity of dataset. among them, ssake runs in rather less time than other peer assemblers, but the ram usage increases dramatically with augmentation of dataset size. qsra is developed upon the original vcake algorithm, which indeed reduces the computational time, at the cost of ram occupation. sharcgs runs in comparable speed as qsra, however it is highly […]
