%description
We develop a novel matrix factorization tool named 'scINSIGHT' to jointly
analyze multiple single-cell gene expression samples from biologically
heterogeneous sources, such as different disease phases, treatment groups,
or developmental stages. Given multiple gene expression samples from
different biological conditions, 'scINSIGHT' simultaneously identifies
common and condition-specific gene modules and quantify their expression
levels in each sample in a lower-dimensional space. With the factorized
results, the inferred expression levels and memberships of common gene
modules can be used to cluster cells and detect cell identities, and the
condition-specific gene modules can help compare functional differences in
transcriptomes from distinct conditions. Please also see Qian K, Fu SW, Li
HW, Li WV (2022) <doi:10.1186/s13059-022-02649-3>.
