Answer: A: clonal populations in cancer samples
... To answer your question in a simple sentence - In an ideal scenario, variants with VAF around 50% is fully clonal. Since most somatic mutations tend to be heterozygous, a clonal mutation would have an allele frequency of 50%. Anything below ~45/40% would be a sub-clonal. But it also depends on your ...

Comment: C: detecting mutations in cancer samples belonging to the same cancer type
... If you have only tumor samples, no matter how much of a sophisticated algorithm you use - there is always an uncertainty associated with the somatic status of an identified variant. Having said that, MuTect can still call somatic variants without gremline controls. But again you will have to be care ...

Answer: A: Software to analyse mutational signatures other than DeconstructSigs R package
... There are few other tools. DeconstructSigs estimates loading of known signatures for every sample in the cohort. If you are interested in de-novo you could try [EMu](http://www.sanger.ac.uk/science/tools/emu) and [Mutational Signature framework](https://www.mathworks.com/matlabcentral/fileexchange/3 ...

Answer: A: how to decide whether a mutation is driver for a specific cell line
... Hi, Whether a gene is a driver or not is usually done on large cohorts based on how frequently the gene is mutated. There are algorithms to identify such genes. How many cell lines do you have in your file ? In case if you're only interested in a particular mutation, - you will have to look at ...
