In this version, we introduce LABRATsc, a tool for quantifying APA from single cell RNAseq data. LABRATsc relies on alevin just as LABRAT relies on salmon.
LABRATsc quantifies differences in APA across predefined populations or clusters of cells. Similar to LABRAT, it calculates gene level psi values as a measure of relative APA site use. It then compares those psi values across predefined clusters of cells and identifies genes whose APA status changes across clusters. The documentation for LABRATsc is included at the bottom of the README file for LABRAT.
