If you have multiple conditions in your data, turn this on to have all samples in that condition included.
Example:
- Sample1: young-control
- Sample2: young-experiment
- Sample3: old-control
- Sample4: old-experiment
To select cells from Sample1 and Sample2, enter “young” into the Condition field and set the Multiple button to True (on). Otherwise, Sample1 and Sample2 must be specified by entering “young-control,young-experiment” into the Condition field.
