cdhit: A function to execute CD-HIT

In kendomaniac/docker4seq: Running NGS computing demanding applications, e.g reads mapping and counting, wrapped in docker containers

A function to execute CD-HIT

Description

This function executes a ubuntu docker that cluster minION sequences using CD-HIT

Usage

cdhit(
  group = c("sudo", "docker"),
  scratch.folder,
  data.folder,
  identity.threshold = 0.9,
  memory.limit = 30000,
  threads = 0,
  word.length = 7
)

Arguments

group	a character string. Two options: sudo or docker, depending to which group the user belongs
scratch.folder	a character string indicating the path of the scratch folder
data.folder	a character string indicating the folder where input data are located and where output will be written
identity.threshold	sequence identity threshold, default 0.9, this is the default cd-hit's global sequence identity calculated as: number of identical bases in alignment divided by the full length of the shorter sequence
memory.limit	memory limit in MB for the program, default 30000. 0 for unlimitted
threads	number of threads, default 0; with 0, all CPUs will be used
word.length	7 for thresholds between 0.88 and 0.9 for other option see user manual cdhit

Value

Returns two files: a fasta file of representative sequences and a text file of list of clusters
