VizSciFlow - Quick Start Guide

VizSciFlow is a workflow management system. It is derived from VizSciFlow system.

It writes workflows using a domain-specific language (DSL).

The DSL has simple syntax and a minimal set of keywords. The syntax has similarities to python’s syntax and indenting.

Scientists can write a workflow script using the visual elements offered in VizSciFlow web interface.

Practice Example Task: Quality Checking and Visualization of Gene Sequence Data

  1. Search "Check Quality" or FastQC in "Services" panel and double click it.
  2. Delete the data parameter and leave the cursor there.
  3. Search F3D6_S194_L001_R1_001.fastq in data sources and use right-click context menu to copy to editor.
  4. Your code editor should look like the following: 
    
fq_html = fastqc.CheckQuality('/public/MiSeq_SOP/F3D6_S194_L001_R1_001.fastq')
  5. Click "Run" from commands panel.
  6. A new item will be added to the top of "Job Histories" panel. Double click it.
