add subsample method #88

Closed gregcaporaso closed 6 years ago

gregcaporaso commented 6 years ago

Addition Description Implement a new action for creating a random subsample of demultiplexed sequence data as a user-specified percentage of the input data.

Current Behavior We use similar subsets of these data for our tutorials, but have generated them externally to QIIME 2 to date.

Proposed Behavior User will provide SampleData[SequencesWithQuality] and a percentage of the sequences to random retain. A new SampleData[SequencesWithQuality] will be generated with roughly (for the sake of computational efficiency) that number of sequences.
