findTrans.func {aCGH} | R Documentation |
This function identifies the start and end of the states (regions with the constant estimated copy number).

outliers |
Binary matrix of the outliers (generally output of the

Binary matrix of the focal aberrations (generally output

The transitions end is placed at the last non-focal aberration clone of the contiguous region containing clones belonging to the same state and transitions start is placed at the first non-focal aberration clone of the contiguous region containing clones belonging to the same state.
trans.matrix |
Matrix with a row for each clone and column for each sample. The starts of the states are indicated by "1" , the end are by "2" and the focal aberrations are coded as "3" |
translen.matrix |
Matrix with a row for each clone and column for each sample. The entries are the length of the region to which a clone belongs. Zero length is assigned to the focal aberrations. This output may be buggy at the moment. |
