Probability (Double in [0-1] or NaN)
The score stemming from the SVM. Higher score corresponds to a better PSM than a lower score.
The PSMs q-value, i.e. the expected fraction of incorrect identifications up to this PSM score
The Protein empirical q-value, i.e. the expected fraction of incorrect identifications up to this Protein score
The PSMs posterior error probability, i.e. the probability that this PSM is incorrect.
The experimental (observed) mass of the PSM
The calculated mass of the PSM
