Bin count targeted normalization using K-mean clustering to group bins with similar coverage profile across the samples. For outlier bins, i.e. showing unique profile, the set of most similar bins is computed for each bin. Eventually the importance of each sample in the definition of the coverage profile can be weighted using principal components. This normalization is still in development state. It is supposed to be more faster than the full targeted normalization ('tn.norm') and better normalize outlier samples (e.g. if the data is not homogeneous).
1 2 |
bc.ref |
a data.frame with the coverage in the reference samples. |
samp |
the name of the sample to normalize. |
bc.to.norm |
If non-null and the 'samp' is not in 'bc.ref', this data.frame is used. It should be a single sample coverage data.frame, i.e. with columns exactly: chr, start, end and bc. |
cont.sample |
the name of the control sample to normalize the coverage to. |
pca.weights |
should the samples be weighted using principal components. |
max.size |
the maximum size of a cluster of bins. |
plot |
should some graphs be outputed ? Default FALSE. |
a data.frame with the normalized bin counts. columns: chr, start, end, bc.
