Method and device for preparing data for identifying analytes

A method for preparing data for identifying analytes by coloring one or more analytes with markers in multiple coloring rounds, the markers in each case being specific for a certain set of analytes, detecting multiple markers using a camera, which for each coloring round generates at least one image containing multiple pixels and color values assigned thereto, which may contain color information of one or more markers, and storing the color information of the particular coloring rounds for evaluating the color information, a data point in each case including one or more contiguous pixels in the images of the multiple coloring rounds that are assigned to the same location in a sample,

• wherein
• for each data point of a sample, the color value for one of n coloring rounds of an experiment is recorded in each case, and these color values in each case form a component of an output vector having the dimension m, after recording the corresponding color value the individual vector components being projected onto a projection vector having a dimension k that is smaller than m, and the projection vector for each coloring round being sequentially aggregated onto an aggregation vector having the same dimension k as the projection vector, and the aggregation vector is stored.
