TitanCNA-dataset: TITAN EM trained results for an example dataset

In gavinha/TitanCNA: Subclonal copy number and LOH prediction from whole genome sequencing of tumours

Description

Data for chromosome 2 for a triple-negative breast cancer dataset and the expectation-maximization (EM) trained results. Only 20,000 datapoints are included and the data has been scrambled to anonymize patient SNPs.

data

Processed input data that is first generated by loadAlleleCounts, and includes log ratios that have been GC content and mappability corrected using correctReadDepth

.

convergeParams

EM results that are generated by runEMclonalCN

Usage
