PROGRAM:
NAME
sumaclust - star clustering of genetic sequences
SYNOPSIS
sumaclust [options] <dataset>
DESCRIPTION
With the development of next-generation sequencing, efficient tools are needed to handle
millions of sequences in reasonable amounts of time. Sumaclust is a program developed by
the LECA. Sumaclust aims to cluster sequences in a way that is fast and exact at the same
time. This tool has been developed to be adapted to the type of data generated by DNA
metabarcoding, i.e. entirely sequenced, short markers. Sumaclust clusters sequences using
the same clustering algorithm as UCLUST and CD- HIT. This algorithm is mainly useful to
detect the 'erroneous' sequences created during amplification and sequencing protocols,
deriving from 'true' sequences.
OPTIONS
-h [H]elp - print <this> help
-l : Reference sequence length is the shortest.
-L Reference sequence length is the largest.
-a Reference sequence length is the alignment length (default).
-n Score is normalized by reference sequence length (default).
-r : Raw score, not normalized.
-d : Score is expressed in distance (default : score is expressed in similarity).
-t ##.## : Score threshold for clustering. If the score is normalized and expressed in
similarity (default),
it is an identity, e.g. 0.95 for an identity of 95%. If the score is normalized and
expressed in distance, it is (1.0 - identity), e.g. 0.05 for an identity of 95%.
If the score is not normalized and expressed in similarity, it is the length of the
Longest Common Subsequence. If the score is not normalized and expressed in
distance, it is (reference length - LCS length). Only sequences with a similarity
above ##.## with the center sequence of a cluster are assigned to that cluster.
Default: 0.97.
-e Exact option: A sequence is assigned to the cluster with the center sequence
presenting the highest similarity score > threshold, as opposed to the default
'fast' option where a sequence is assigned to the first cluster found with a center
sequence presenting a score > threshold.
-R ## Maximum ratio between the counts of two sequences so that the less abundant one can
be considered as a variant of the more abundant one. Default: 1.0.
-p ## Multithreading with ## threads using openMP.
-s ####
Sorting by ####. Must be 'None' for no sorting, or a key in the fasta header of
each sequence, except for the count that can be computed (default : sorting by
count).
-o Sorting is in ascending order (default : descending).
-g n's are replaced with a's (default: sequences with n's are discarded).
-B ### Output of the OTU table in BIOM format is activated, and written to file ###.
-O ### Output of the OTU map (observation map) is activated, and written to file ###.
-F ### Output in FASTA format is written to file ### instead of standard output.
-f Output in FASTA format is deactivated.
