Hey there,

Using exomeCopy for CNV detection. Was wondering how to get the posterior probabilities that determine the path. I thought that the vector, "V", returned by the C function inside viterbiPath() was what I was looking for but when I calculate the most likely path using "V" it differs in a handful of exons/targets from what is returned by viterbiPath(). Do I need to multiply "V" by something to get the posteriors?

Thanks!

We only return the Viterbi path. But you have the ‘log.odds’ vector as well, from ?”ExomeCopy-class”:

“the log ratio of the emission probabilities along the predicted path over the emission probabilities of the normal state”
