The bioinformatics app: Powerful, easy-to-use and free.
Preprocessing | Alignment & Mapping | Variant Calling & Discovery | Annotations | Interpretations | Conversions
Create your own pipeline in seconds. Use defaults or define specific parameters. It's your choice!
Meet EvE, the first universal genetic adaptor that aligns, calls, annotates, converts and interprets almost any genetic data file to EvErything. EvE includes a straightforward user interface and powerful, dynamic processing so that using your custom EvE pipeline is effortless and fast.
With EvE, you can create your own custom pipeline within seconds. For example, you can select Isaac for alignment and SamTools for variant calling. Or you can select CutAdapt for pre-processing, TopHat2 for alignment, Isaac for variant calling and SnpEff for annotation. Once you select your pipeline, you can use defaults or easily modify almost any parameter.
You no longer have to worry about whether your computer hardware and servers are powerful enough to process your data. With EvE, you also don't have to worry about bandwidth charges or obscure cloud computing fees. All you need is an internet connection (such as from a laptop or mobile device) and EvE will process your genetic data.
There are three editions of EvE:
1. EvE Free (this app)
- Cost: Free
- Performs all pre-processing, alignments, variant discovery, annotations and conversions.
- With just a few clicks, EvE will process your data.
- EvE's Default Settings processes data according to most-often-used settings while Advanced Settings allow you to define most parameters.
- Select any human reference genome from hg2 through GRCh38.p6 or simply use the default 'Auto Detect'
- Reference Genome Auto Detect
- automatically uses GRch38.p6 if your pipeline includes alignment

- -C, --adjust-MQ INT: Coefficient for downgrading mapping quality for reads containing excessive mismatches. Given a read with a phred-scaled probability q of being generated from the mapped position, the new mapping quality is about sqrt((INT-q)/INT)*INT. A zero value disables this functionality; if enabled, the recommended value for BWA is 50. 
- -d, --max-depth INT:At a position, read maximally INT reads per input BAM. 
- -E, --redo-BAQ: Recalculate BAQ on the fly, ignore existing BQ tags

Output Options for VCF/BCF format (with -g or -v):

- -L, --max-idepth INT
- -m, --min-ireads INT: Minimum number gapped reads for indel candidates INT. 
- -o, --open-prob INT: Phred-scaled gap open sequencing error probability. Reducing INT leads to more indel calls.

- -P, --platforms STR: Comma-delimited list of platforms (determined by @RG-PL) from which indel candidates are obtained. It is recommended to collect indel candidates from sequencing technologies that have low indel error rate such as ILLUMINA. [all]

When you use EvE, your data files and result file(s) will be stored in your Sequencing.com account, which provides free, unlimited storage of genetic data.
This simple yet secure approach means you no longer have to use your own storage or computing power to conduct genetic analysis and you also no longer have to use USB drives or FTP sites to move and share genetic data.
EvE includes an integration of the following:
A suite of programs for interacting with high-throughput sequencing data. It consists of three separate repositories:
- Samtools: Reading/writing/editing/indexing/viewing SAM/BAM/CRAM format
- BCFtools: Reading/writing BCF2/VCF/gVCF files and calling/filtering/summarising SNP and short indel sequence variants
- HTSlib: A C library for reading/writing high-throughput sequencing data
GATK (Genome Analysis Toolkit)
GATK analyzes high-throughput sequencing data. The toolkit, which focuses on providing high quality data, offers a wide variety of tools including variant discovery and genotyping.
Isaac Variant Caller
Isaac Variant Caller (IVC) is an analysis package designed to detect SNVs and small indels from the aligned sequencing reads of a single diploid sample.
SnpEFF predicts the effects of genetic variations and also provides annotations. Annotations can simple such as variant name or more complex such as site of variation such as exon, intron and its effect on gene expression.
Since EvE offers conversions between different file formats such which is a multistep process at time, we use our own scripts to pipe data and create some file types.
The following use custom scripts developed by Sequencing.com:
- Clinical plus VCF file generation
- gVCF to VCF conversion
- csv and txt conversion to vcf
- Includes 23andMe, Ancestry.com, National Geographic, Genes for Good and other companies that provide genetic data as csv and txt files
- vcf conversion to csv and txt
- Data is converted into csv files compatible with 23andMe format
Wormtable is a format for storing large scale tabular data and interacting with it. It generates an index file as well that can be used repeatedly. Wormtable files are considered very Python friendly and can be used in downstream Python based analysis.
GVF (Genome Variation Format) is gaining popularity as a standard for sequence ontology based datasets. It is a successor of the GFF3 format and includes pragmas for defining sequence alterations at genomic locations as compared to the reference genome.
Human clinical applications require sequencing information for both variant and non-variant positions, yet there is currently no common exchange format for such data. Genomic VCF (gVCF) addresses this issue. gVCF is a set of conventions applied to the standard variant call format (VCF) that include genotype, annotation and other information across all sites in the genome in a reasonably compact format.
