For the Helmholtz Imaging project UCS (Ultra Content Screening for Clinical Diagnostics and Deep Phenotyping) we developed software to allow the project partners to process their immunofluorescence labelled light microscopy data of nuclei and cells for single cell proteomics. The developed pipeline includes instance segmentation of nuclei and cells in the immunofluorescence assays, registration of the images and the respective quantitative analysis. Within 2021 the project has been provided with a first prototype implementation of the software. Testing and refinement are still ongoing depending on the data acquired.
