DeconSeq. DECONtamination of SEQuence data.
Detect and remove contaminations
from your sequence data.
The DeconSeq tool can be used to automatically detect and efficiently remove sequence contaminations from genomic and metagenomic datasets. It is easily configurable and provides a user-friendly interface.
Input interface
The user can upload FASTA or FASTQ files and select the databases used for contamination screening, including seven human genomes, bacterial genomes, and viral genomes.
Interactive threshold selection
The user can set the thresholds interactivly and see the results directly using the functionality of the graphical interface. The results can be downloaded in joined or separated files in different formats.
Coverage-Identity plots
The coverage-identity plots provide additional information that can guide the selections of the thresholds using color coded points and connecting lines.
