Download Land Data For All Comparisons, For Selected Genes (Local analyses)

The function allows users to retrieve data for all genes for a list of comparisons, as OmicData/Table to a Local Analysis project.

Options

  • Land: the land data to query input genes
  • Project: the target ArrayStudio project to store downloaded Land data
  • ComparisonSet: specify a collection of comparisons (comparisonSet) or get all comparisons
  • VariableSet: specify a collection of columns (variableSet) or get none/all columns from sample meta data. Selected metadata will be downloaded as a table in the project. By default, only PrimaryGrouping and SecondaryGrouping columns are attached as design in each generated OmicData.
  • Input comparisons: a list of comparisons to query. Comparisons can also be loaded from Comparison
  • Output name: name prefix for download data objects

Output

Downloaded data will be listed in the targeted project. These omic data will be saved as in-file rather than in-memory. If majority of the data matrix are zeros, such as feature * sample matrix for fusion, mutation and junction, the Omic data will be saved as sparse matrix data. These improvements significantly reduce memory usage by sacrificing little performance (data loading speed).
