Dataset selection

This page uses BrAPI calls to select a dataset from the GOBii-GDM database. The pull-down menu lists all of the datasets in this GOBii-GDM instance.

• Select a dataset to view

• Summary metrics (number of samples and markers) for the dataset are displayed 

• Click on the View button to see your dataset

Visualization of Genotyping Data

• The genotyping data visualization uses standard Flapjack nucleotide coloring and data labeling

  • White blocks indicate missing data

  • Currently there is not an option to import a map (but we will have this feature in future), and so markers are listed in the order that they were loaded to the dataset, with equal spaced position

  • The sample name (equivalent to the dnarun_name in GOBii terms) is listed down the side of the dataset

• If you scroll to the bottom of the page, you will see a zoom bar. Move the zoom bar to the right to get a closer look at the data

• You can also exit the visualization page and return back to the dataset selection page by clicking 'back to VariantSet selection'. A VariantSet is another name for dataset
