Abstract
Some embodiments of the methods provided herein relate to sample analysis and particle characterization methods for large, multi-parameter data sets. Frequency difference gating compares at least two different data sets to identify regions in a multivariate space where a frequency of events from a first data set is different than a frequency of events from the second data set according to a defined threshold.
Claims20
A computer-implemented method of visualizing differences between n-dimensional data sets, the computer-implemented method comprising:
- under control of one or more processing devices,
- performing frequency difference gating on a first data set of n-dimensional data and a second data set of n-dimensional data, wherein the n-dimensional data comprises a plurality of events in a plurality of dimensions;
- and
- generating a visualization from the frequency difference gated data for display via a display device, the visualization showing regions in a multivariate space where a frequency of events from the first data set is different than a frequency of events from the second data set according to a defined threshold.

A system comprising:
- one or more processing devices;
- and
- a computer-readable storage medium comprising instructions that, when executed by the one or more processing device, cause the system to:
- receive a threshold for frequency difference gating received data sets;
- receive a first data set of n-dimensional data including a first plurality of events in a plurality of dimensions;
- receive a second set of n-dimensional data including a second plurality of events in at least the plurality of dimensions;
- identify a frequency difference gate defining a population of events based at least in part on frequency difference gating for the first data set of n-dimensional data and the second data set of n-dimensional data, the gate identifying a region in multivariate space where a frequency of events from the first data set is different than a frequency of events from the second data set according to the threshold;
- and
- cause display of a visualization including a representation of events from the first data set and the second data set included in the population defined by the frequency difference gate, the visualization showing regions in the multivariate space where the frequency of events from the first data set is different than the frequency of events from the second data set according to the threshold.
