As single-cell multi-omics studies scale in size and complexity, comprehensive and modality-aware quality control (QC) is essential to ensure data integrity. Here, we develop SingleCellMQC, an open-source R package that provides a unified QC framework for single-cell RNA sequencing (scRNA-seq), surface proteome profiling (antibody-derived tags, ADTs), and immune repertoire (T cell receptors [TCRs]…
