Abstract

Features for a quantitative biological data analysis system are described. Index sort analysis can be performed using sort electronics on a flow cytometer or other particle analysis system or after an experiment using a workstation. The sort electronics on the cytometer or other particle analysis system may generate sort decision information for the events. The sort decision information may be transmitted from the sort electronics to the workstation that may differ from the sort identified by the workstation. The feature fuse the gate information with the sorting decision information to provide an accurate representation of the sorting.

First claim

What is claimed is:

1 . A computer-implemented method of fused gating for index sorting, the method comprising:
under control of one or more electronic processors: receiving, at a workstation from a memory, experiment information identifying:
(i) a first sort gate,
(ii) a first plate destination for particles identified within the first sort gate on a collection plate,
(iii) a second sort gate, and
(iv) a second plate destination for particles identified within the second sort gate on the collection plate;
generating, at the workstation, a first index sort inclusion bitmap identifying first plate locations on the collection plate using the first sort gate; generating, at the workstation, a second index sort inclusion bitmap identifying second plate locations on the collection plate using the second sort gate; receiving, at the workstation, event data for the particles, the event data including for each particle a fluorescent parameter value and a sort decision of a sorting device; determining, via the workstation, that an individual fluorescent parameter value for an individual particle included in the particles is within the first sort gate; associating the individual particle with the first sort gate for presentation via a user interface; determining, via the workstation, that an individual sort decision for the individual particle corresponds to the second sort gate based at least in part on a comparison between the individual sort decision and the second index sort inclusion bitmap; and associating the individual particle with the second sort gate for presentation via the user interface.

2 . The computer-implemented method of claim 1 , wherein the sort decision is generated by a sorting device configured to sort the particles into the collection plate based at least in part on the experiment information.

3 . The computer-implemented method of claim 1 , further comprising: receiving, at the workstation, a geometric shape defining the first sort gate, wherein the geometric shape is pixelated.

4 . The computer-implemented method of claim 1 , further comprising: receiving, at the workstation, a request to adjust an axis for a geometric shape defining the first sort gate, wherein the geometric shape, after the axis is adjusted, is pixelated.

5 . The computer-implemented method of claim 4 , wherein the request includes a binomial transformation to adjust the axis.

6 . The computer-implemented method of claim 1 , wherein the first sort gate identifies a set of particles having parameter values distinct from another set of particles identified by the second sort gate.

7 . An apparatus comprising:
a particle analyzer configured to acquire quantitative biological event data; one or more processors in communication with the particle analyze, the one or more processors configured to: receive, from a memory, experiment information identifying:
(i) a first sort gate,
(ii) a first plate destination for particles identified within the first sort gate,
(iii) a second sort gate, and
(iv) a second plate destination for particles identified within the second sort gate;
generate a first index sort inclusion bitmap uniquely identifying the first sort gate; generate a second index sort inclusion bitmap uniquely identifying and the second sort gate; receive, from the particle analyzer, event data for the particles, the event data including for each particle a fluorescent parameter value and a sort decision; determine that an individual fluorescent parameter value for an individual particle included in the particles is within the first sort gate; associate the individual particle with the first sort gate for presentation via a user interface; determine that an individual sort decision for the individual particle corresponds to the second sort gate based at least in part on a comparison between the individual sort decision and the second index sort inclusion bitmap; and associate the individual particle with the second sort gate for presentation via the user interface.

8 . The apparatus of claim 7 , wherein the sort decision is generated by the particle analyzer, wherein the particle analyzer is configured to sort the particles into the plate based at least in part on the experiment information.

9 . The apparatus of claim 7 , wherein the one or more processors are further configured to: receive a geometric shape defining the first sort gate, wherein the geometric shape is pixelated.

10 . The apparatus of claim 7 , wherein the one or more processors are further configured to: receive a request to adjust an axis for a geometric shape defining the first sort gate, wherein the geometric shape, after the axis is adjusted, is pixelated.

11 . The apparatus of claim 10 , wherein the request includes a non-linear transformation to adjust the axis.

12 . The apparatus of claim 7 , wherein the first sort gate identifies a set of particles having parameter values distinct from another set of particles identified by the second sort gate.

13 . The apparatus of claim 7 , wherein the one or more processors are further configured to:
cause display of a graphic representation of the plate, the graphic representation of the plate including a first area representing the second plate destination; and cause display of a graphic indicator for the individual particle within the first area.

14 . A computer-readable medium having stored thereon instructions which when executed by a processor of a device, cause the device to at least:
receive, from a memory, experiment information identifying:
(i) a first sort gate,
(ii) a first plate destination for particles identified within the first sort gate,
(iii) a second sort gate, and
(iv) a second plate destination for particles identified within the second sort gate;
generate a first index sort inclusion value uniquely identifying the first sort gate; generate a second index sort inclusion value uniquely identifying and the second sort gate; receive, from a particle analyzer, event data for the particles, the event data including for each particle a fluorescent parameter value and a sort decision; determine that an individual fluorescent parameter value for an individual particle included in the particles is within the first sort gate; associate the individual particle with the first sort gate for presentation via a user interface; determine that an individual sort decision for the individual particle corresponds to the second sort gate based at least in part on a comparison between the individual sort decision and the second index sort inclusion value; and associate the individual particle with the second sort gate for presentation via the user interface.

15 . The computer-readable medium of claim 14 , wherein the sort decision is generated by a sorting device configured to sort the particles into the plate based at least in part on the experiment information.

16 . The computer-readable medium of claim 14 , further having stored thereon instructions which when executed by the processor of the device, cause the device to at least to: receive a geometric shape defining the first sort gate, wherein the geometric shape is pixelated.

17 . The computer-readable medium of claim 14 , further having stored thereon instructions which when executed by the processor of the device, cause the device to at least to: receive a request to adjust an axis for a geometric shape defining the first sort gate, wherein the geometric shape, after the axis is adjusted, is pixelated.
