Source Code: https://github.com/nconrad/mauve-viewer
Services¶
PATRIC services provide simple, integrated access to computational software for processing and analysis of raw data and common data types. Access is provided via the Services top menu which displays a simple submission form for each service. In order to use most of the services, the user must be logged in (denoted by “Login required” at the end of the descriptions below). This is required in order to accommodate user upload of their data and longer, more computationally intensive analyses on HPC machines. The results of the service are deposited in the user’s workspace. A few of the services, such as BLAST, do not require login and instead render the results appropriately in the website.
Source Code:
Submission forms: https://github.com/PATRIC3/p3_web/tree/master/public/js/p3/widget/app
Application Execution Service: https://github.com/PATRIC3/app_service
Note: All of the standalone computational services are dependent on app_service. For services below for which no other repos are listed (e.g., Variation Analysis, Metagenomic Read Mapping, Taxonomic Classification, Protein Family Sorter, Comparative Pathway, and ID Mapping) app_service includes all PATRIC code required for the service, plus possibly other third party command line tools.
Also required for all services:
Genome Assembly Service¶
The Genome Assembly Service can be used to perform an automated genome assembly using the latest computational tools. Single or multiple assemblers can be invoked to compare results. The assembly service attempts to select the best assembly—i.e., assembly with the smallest number of contigs and the longest average contig length. Several assembly workflows or “recipes” are available. These workflows have been tuned and tested to fit certain data types or desired analysis criteria such as throughput or rigor. The assembly service’s flexible nature also enables the rapid design and emulation of other popular protocols. Login required.
Genome Annotation Service¶
The Genome Annotation Service is based on the RAST Toolkit (RASTtk). RASTtk is a modular extensible genome annotation system that provides mechanisms for identifying genomic features and annotating their functions. The RASTtk annotation engine uses a signature k-mer method to propagate annotations taken from the CoreSEED, a genome annotation system that has been central to the quality of the RAST annotations over the years. The CoreSEED curation process takes advantage of subsystems-based annotation to ensure high-quality, consistent annotations. RASTtk is fully defined at http://www.ncbi.nlm.nih.gov/pubmed/25666585. Links and instructions for downloading and installing RASTtk client code are included. The subsystems annotation method is described at http://nar.oxfordjournals.org/content/33/17/5691.full. Login required.
Comprehensive Genome Analysis Service¶
The Comprehensive Genome Analysis Service provides a streamlined analysis “meta-service” that accepts raw reads and performs a comprehensive analysis including assembly, annotation, identification of nearest neighbors, a basic comparative analysis that includes a subsystem summary, phylogenetic tree, and the features that distinguish the genome from its nearest neighbors. Login required.
BLAST Service¶
The PATRIC BLAST service integrates the BLAST (Basic Local Alignment Search Tool) algorithms to perform searches against public or private genomes in PATRIC or other reference databases using a DNA or protein sequence and find matching genomes, genes, RNAs, or proteins.
Similar Genome Finder¶
The Similar Genome Finder Service will, for a user-selected genome or for an uploaded FASTA file, find the closest related public genomes (by sequence) in PATRIC using the MInHash algorithm to perform comparisons. Login required.
Variation Analysis Service¶
The Variation Service can be used to identify and annotate sequence variations using a variety of aligner and SNP calling programs. The service enables users to upload one or multiple short read samples and compare them to a closely related reference genome. For each sample, the service computes the variations against the reference and presents a detailed list of SNPs, MNPs, insertions and deletions with confidence scores and effects such as “synonymous mutation” and “frameshift”. High confidence variations are downloadable in the standard VCF format augmented by SNP annotation. A summary table illustrating how the variations are shared across the samples is also available. Login required.
Tn-Seq Analysis Service¶
The Tn-Seq Analysis Service allows users to align reads and measure essentiality of their Tn-Seq data using the TRANSIT software. The results can be downloaded or viewed as alignments to the reference genome in the Genome Browser. The alignments are presented as a separate track in the Genome Browser along with annotated genes. Login required.
Phylogenetic Tree Service¶
The Phylogenetic Tree Service enables construction of custom phylogenetic trees for up to 50 user-selected genomes. The service builds trees using conserved protein sequences, which is the same methodology used to build the public genus-level phylogenetic trees in the PATRIC website. The service also provides an option for building a codon tree. Users can view or download a Newick file, or access the new tree in the interactive Phylogenetic Tree Viewer in PATRIC. Login required.
Codon tree: https://github.com/PATRIC3/codon_trees
Shared proteins: https://github.com/PATRIC3/pepr
Genome Alignment Service¶
The Whole Genome Alignment Service aligns genomes using progressiveMauve to create whole genome alignments of up to 20 genomes. Login required.
Metagenomic Read Mapping Service¶
The Metagenomic Read Mapping Service uses KMA to align reads against antibiotic resistance genes from CARD and virulence factors from VFDB. Login required.
Taxonomic Classification Service¶
The Taxonomic Classification Service accepts reads or contigs from sequencing of a metagenomic sample and uses Kraken 2 to assign the reads to taxonomic bins, providing an initial profile of the possible constituent organisms present in the sample. Login required.
Metagenomic Binning Service¶
The Metagenomic Binning Service accepts either reads or contigs, and attempts to “bin” the data into a set of genomes. This service can be used to reconstruct bacterial and archael genomes from environmental samples. Login required.
Expression Import Service¶
The Expression Import Service allows users to upload differential expression data into their private workspace and compare it with other expression data available in PATRIC. The service supports gene expression, protein expression, and phenotype array data in the form of log ratios, generated by comparing samples, conditions, or time points. Login required.
RNA-Seq Analysis Service¶
The RNA-Seq Analysis Service provides tools for aligning, assembling, and testing differential expression on RNA-Seq data. Three recipes for processing RNA-Seq data are included: 1) Rockhopper, based on the popular Rockhopper tool for processing prokaryotic RNA-Seq data; 2) Tuxedo, based on the tuxedo suite of tools (i.e., Bowtie, Cufflinks, Cuffdiff); and 3) Host HISTAT2 for analyzing RNA-Seq datasets from host (human, mouse, etc.) in support of dual RNA-Seq. The service provides SAM/BAM output for alignment, tab delimited files profiling expression levels, and differential expression test results between conditions. Login required.
Included RNA-Seq tools:
Protein Family Sorter Service¶
The Protein Family Sorter Service tool enables researchers to examine the distribution of protein families across a set of user-selected genomes. Results are displayed in a page showing all the families associated with the selected genomes, plus filter controls and an interactive heatmap.
Proteome Comparison Service¶
The Proteome Comparison Service performs protein sequence-based genome comparison using bidirectional BLASTP. This service allows users to select up to 8 genomes (either public or private) and compare them to a user selected reference genome. The service also allows users to upload an external genome file in FASTA format for an additional comparison. The genome comparison result is displayed as an interactive circular genome view on the webpage. Both the SVG image and the bidirectional BLASTP comparison results can be downloaded. Login required.
Comparative Pathway Service¶
The Comparative Pathway Service allows users to identify a set of pathways based on taxonomy, EC number, pathway ID, pathway name and/or specific annotation type.
Model Reconstruction Service¶
The Model Reconstruction Service allows users to construct their own metabolic model for any genome in PATRIC. The service includes support for model gap-filling, flux balance analysis, essential gene prediction, and export of models in SBML format. The service leverages capabilities of the ModelSEED (PMID: 20802497). Login required.
ID Mapper Service¶
The ID Mapper Service allows users to map individual or sets of PATRIC identifiers to those from other prominent external databases, such as GenBank, RefSeq, EMBL, UniProt, KEGG, etc. Alternatively, users can start with a list of external database identifiers and map them to the corresponding PATRIC features.
