1. A system for encoding and storing mass spectrum data acquired using data independent acquisition, the system comprising:
a processor;
a non-transitory memory in communication with the processor and storing instructions that, when executed, cause the processor to:
obtain the mass spectrum data including counts or intensities for one or more product ions in each window of a series of transmission ion windows;
detect a unique product ion in the mass spectrum data;
identify one or more windows in the series in which the unique product ion appears; and
record, for each window of the one or more windows, a position of the window and a sum of counts or intensities for a group of windows spanning the window.
