LoadExperiment

LoadExperiment enables you to load a set of experimental quantitative, polymorphism, or alignment data for a genome in CoGe. Several different file formats are supported. The data can then be viewed alongside annotation in GenomeView.

Inputs

Metadata

• Name: Name of experiment
• Description: Description of experiment
• Version: Version of experiment
• Source: Where is the data from? This could be you, your lab, your university, a sequencing center, your collaborator.
• Restricted: Is this experiment public or restricted to you and your collaborators
• Genome: Select the appropriate genome from CoGe
• Select Data File: Opens a window for specifying the input data file

Data File

You can select and retrieve data file located at:

• The iPlant Data Store
• An FTP server
• Your computer (Upload)
  

Data Formats

LoadExperiment supports several data file formats depending on the data type:

• Quantitative data
  • Comma-separated (CSV) file format
  • Tab-separated (TSV) file format
  • BED file format
• Polymorphism (SNP) data
  • Variant Call Format (VCF) file format
• Alignment data
  • BAM file format

Each of these file formats are described below in their own section.

CSV File Format

This is a comma-delimited file that contains the following columns

• Chromosome (string)
• Start position (integer)
• Stop position (integer)
• Chromosome Strand (1 or -1)
• Measurement Value must be between [1-0] (real number; inclusive)
• Second Value (OPTIONAL): can store a second value such as an expect value (real number)

TSV File Format

Same as CSV format but with tab delimiters instead of commas.

BED File Format

Standard BED format as defined here: http://genome.ucsc.edu/FAQ/FAQformat.html#format1

Only the first six columns are used, with the "name" field ignored.
