OMSSA noise filter improvements. This figure compares the different options in OMSSA noise filter (h1 and h2) for spectra searched for 3 ion species. By default, OMSSA sets a value of 2 for these parameters. Looking at the ROC plot, we modified these parameters "h1" and "h2" to be equal to the number of ions searched for, to yield higher sensitivity without loss in specificity.
