Examples

The following example defines "Track statistics" analysis method:

<extension id="Track statistics" point="ru.biosoft.analysis.method"> 
  <analysisClass
    class="ru.biosoft.bsa.analysis.stats.SequenceStatistics"
    group="BSA"
    name="Track statistics"
    description="Gather various statistics about track or FASTQ file"
    js="siteAnalysis.trackStats"/> 
</extension>

JavaScript implementation

JavaScript analysis implementation will be automatically generated if you perform the following steps:

• Create JavaScript host object class which extends ru.biosoft.analysis.javascript.JavaScriptAnalysisHost.
• Register it via hostObject extension point.
• Add "js" attribute with registered host object name and desired method name separated by point as "siteAnalysis.trackStats" in the example above.
