Usage

1
getKEGGGeneSeq(KEGGID, seqType = "aaseq", n = 4)

Arguments

KEGGID

A vector of KEGG IDs. Seqences from different species could be combined together.

seqType

Choose nucleotide acid (ntseq) or amino acid (aaseq) seqences, and the default is amino acid sequences.

n

The number of CPUs or processors, and the default value is 4.

Details
