Training set: distribution of likelihood values of fragments (left) and maximal fragments (right). A likelihood value of 100 indicates that the chemical formula of the fragment or maximal fragment is highly likely. Blue: distribution for correctly identified fragments/maximal fragments. Red: distribution for wrongly identified fragments/maximal fragments. In total, there were 353 reconstructed fragments, 343 correct and 10 wrong, and 50 maximal fragments, 44 correct and 6 wrong. Above a likelihood value of 20, >95% of the fragments are correct, and >90% of the maximal fragments
