BACOM2.0 (Bayesian Analysis of COpy number Mixtures) is an improved version of BACOM (see links) package that contains a pipeline for copy number variation (CNV) analysis in heterogeneous cancer cell sample data. BACOM also estimates deletions and tissue contamination. The main improvement consists of an enhanced allele-specific normalization method.
Alternative name: bacomR (an R interface for BACOM Java version).
Note: BACOM2.0 requires original BACOM program (download) to read and process raw SNP array data (.CEL files). See links below.
