Filter samples and select sample grouping for analysis

Note: This step is optional and default is to select all the available samples for analysis.

An experiment may have a number of samples which are organized in different groups (sample subgroupings).

One may wish to restrict analysis only to a subset of all the available samples for an experiment.

This section describes how this is achieved.

Figure: Select samples for analysis

Figure shows the screen to filter samples for experiment GSE10797. We can choose to either include or exclude all the samples that satisfy the criteria we are going to define by selecting appropriate option using the radio button.

All the sample subgroupings are listed in this box. When we click on a sample subgrouping, the link expands to show all the unique values for the same as shown in figure .

Let's say, we want to include only the samples for which Disease is cancer and CellType is epithelial.

Figure: Filter sample example

As shown in figure , select include from the radio button, and check cancer box under Disease and epithelial box under CellType. When you click Analyze, only the samples for this criteria will be used for analysis.

Next step is to select sample grouping for analysis.
