Background:

genome.txt is a tab-delimited file IGB reads and uses to populate the Current Genome tab. When a user selects a species and genome version, IGB reads the genome.txt file.

When users select rows in the table, IGB should display the corresponding chromosome/sequence in the main view.

Example genome.txt file: http://igbquickload.org/quickload/A_thaliana_Jun_2009/genome.txt

Do the following tests. Report results of each test in a separate comment. Attach files used for testing.

For each test:

• select chromosomes and observe IGB behavior
• view console and report any exceptions

Tests:

• test what happens if a chromosome name contains a space
• test what happens if there is a duplicate line in genome.txt
• test what happens if the same chromosome name is listed twice but with different sizes
• test what happens if there is a trailing space after the length column
• test what happens if a non-ASCII (Unicode) character is used in a chromosome name

Across servers:

• test what happens if the same genome version is available at two different QuickLoad sites but they report different sizes for the same chromosome name
• test what happens if the same genome version is available at two different QuickLoad sites but they report different chromosome names
• test what happens if the same genome version is available at two different QuickLoad sites, the chromsome names and sizes are the same, but the order is different
