NanoAmpli-Seq: A workflow for amplicon sequencing from mixed microbial communities on the nanopore sequencing platform.
microbiomeSeq(Ongoing project; Designed with Alfred Ssekagiri): An R Package for multivarite statistical analysis of microbial community analysis in an environmental context.
RvLab(with collaborators at HCMR, Greece) makes use of
Rwhich is a statistical processing environment widely used by scientists working in many biodiversity related disciplines. It supports an integrated and optimized (in respect to computational speed-up and data manipulation) online
Renvironment. This vLab tackles common problems faced by
Rusers, such as severe computational power deficit. Many of the routines operating under the R environment, such as the calculation of several biodiversity indices and the running of the multivariate analyses, are often of high computational demand and cannot deliver a result when the respective datasets are in the form of large matrices.

clust_validity.R: This script takes a CSV file of N D-dimensional features, performs K-means or dp-means clustering and chooses the optimum number of clusters based on either of the implemented internal clustering validation indices. Additionally, if the csv file contains a column titled "True_Clusters" containing true clusters membership for each object, you can use it to validate clustering performance using several external clustering indices.
clust_validity.R(Tutorial, Reference slides (maths), Example datasets)
GraphicalLasso.tar.gz: Generates network of associations between OTUs as a DOT file which can then be visualised in
GNUparallel: For an Illumina dataset with 6 million reads,

blastn.shwhich took 86 minutes.
extract_clust_seqs_fasta.plis an extension of
Typical.pland can give the most abundant sequence, consensus sequence, first sequence, and the longest sequence of each cluster as representative OTU.

convIDs.pl: This script takes a (TAB/COMMA) delimited file and converts words in a particular column to those provided by a COMMA delimited IDs list.
Rscript takes two frequency tables in CSV format and collates them together by either taking union or intersection of columns. Furthermore it inserts "F1_" and "F2_" as prefixes to rownames of both CSV files, respectively.
collateResults.pl: This script is useful for combining CSV files generated by
AMPLICONprocessingor any software that produces two-column CSV files without header information. It takes as an input the path to a main folder where subfolders contain CSV files, each matching a particular pattern in their names.
