JSON Output file
IAE produces an output file in JSON format that includes the following three sections:
Section |
Content |
---|---|
Header |
Configuration, data source versions, and sample names. |
Positions |
Variant level annotation. |
Genes |
Gene level annotation. |
The following are outputs using the example commands specified in the sections above. Each of the following sections contains only a subset of information. The output file contains more information.

The following is an example of the Header section.

Each position represents one row of the VCF file. Each position contains a samples section and a variants section. Reference and alternate alleles shown here matches the VCF content exactly.
The samples section lists the sample-specific information, such as genotype, in the same order as they appear in the VCF and in the JSON header above.
The variants section provides annotations for each alternate allele that appear in the VCF row. This includes allele-specific annotation from external data sources as well as transcript-level annotation. Reference and alternate alleles shown here are shown in their most shortened representation. For example, padding bases have been removed and the variant are left-aligned.

CMS8 is an autosomal recessive disorder characterized by prominent defects of both the pre- and postsynaptic regions. Affected individuals have onset of muscle weakness in early childhood; the severity of the weakness and muscles affected is variable (summary by Maselli et al., 2012).\n\nFor a discussion of genetic heterogeneity of CMS, see CMS1A.",
