For each spot we show the number given by PDQuest software, hypotheses tested in GUHA (metastases = 1, no metastases = 0), cut points estimated from log-normalized density with maximal impurity function decrease, the value of Fisher statistics corresponding to Fisher's exact test (fisher) and maximal false-positive rate approximation among the proteins supposed to be significant (q-value).
