We are excited to introduce a Foreign Contamination Screen (FCS) tool<\/a> that you can now run yourself, with enhanced contaminant detection sensitivity to improve your genome assemblies and facilitate high-quality data submissions to GenBank<\/a>. If you submit genome assembly data to GenBank, the FCS tool is for you!<\/p>\n What is the FCS tool?<\/strong><\/p>\n FCS, a quality assurance process used<\/span><\/span> to make data suitable for submission, consists of two parts: FCS-adaptor<\/a> and FCS-GX<\/a>. FCS-adaptor searches for short sequences that are used as part of the lab preparation process and sometimes wind up in the final assembly by mistake. FCS-GX searches for sequences from a wide range of organisms including bacteria, fungi, protists, viruses, and others to identify sequences that don’t look like they are from the intended organism. In each case, you receive a report of the coordinates and identities of potential contaminants to be reviewed and removed (see Figure 1 for a sample report of the FCS-GX summary output). Both tools are designed to screen both eukaryote and prokaryote genomes.<\/p>\n Figure 1. FCS-GX report showing the summary of contamination identified in a tomato genome. The output indicates there are 83 sequences, adding up to 381 kb total length, to be removed from a mix of insect, fungal, and bacterial sources.<\/em><\/p>\n How do I use FCS?<\/strong><\/p>\n FCS is available from <\/span><\/span>GitHub<\/span><\/span><\/span><\/a>. Simply download the <\/span>two <\/span>programs (FCS-adaptor and FCS-GX), and follow a few steps as outlined in the Quickstart<\/a>. <\/span>Both tools are also easy and inexpensive to run<\/span>\u00a0on commercial clouds such as Amazon Web Services (AWS) or Google Cloud Platform (GCP), and <\/span>can screen genomes in a fraction of the time of other approaches.<\/span><\/span>\u00a0<\/span><\/p>\n Why is FCS important?<\/b><\/p>\n Having high quality data available for analysis is <\/span>necessary<\/span> in order to arrive at accurate conclusions <\/span>during research<\/span>. <\/span>With FCS, r<\/span>apid<\/span> detect<\/span>ion of<\/span> contaminants from foreign organisms in assembled genomes <\/span>ensures <\/span>that <\/span>high value data is being provided for submission and available for reuse. <\/span>We\u2019ve <\/span>already <\/span>used<\/span> FCS-GX <\/span>to <\/span>remove<\/span> over one hundred <\/span>megabases<\/span> of contaminants and thousands of erroneous genes and proteins from previously submitted eukaryote genomes <\/span>to make<\/span> the data more useful for all.<\/span><\/span>\u00a0<\/span><\/p>\n We want to hear from you!<\/strong><\/p>\n We will update the FCS tool based on your feedback, so try it out and let us know what you think. Please contact us<\/a> with comments and suggestions.<\/p>\n FCS is part of the NIH Comparative Genomics Resource (CGR)<\/a>, an NLM project to establish an ecosystem to facilitate reliable comparative genomics analyses\u202ffor all eukaryotic organisms.<\/p>\n Join our mailing list<\/a> to keep up to date with FCS and other CGR news.<\/p>\n \n","protected":false},"excerpt":{"rendered":" We are excited to introduce a Foreign Contamination Screen (FCS) tool that you can now run yourself, with enhanced contaminant detection sensitivity to improve your genome assemblies and facilitate high-quality data submissions to GenBank.
