scoring, minimum ion count
The value is a positive integer.
Practically, there is some minimum number of assignable sequence-specific ions in a spectrum that is necessary to consider the spectrum as a match to a peptide sequence. The value of this parameter sets the minumum number of total ions that must be assigned for a score to be calculated and stored in the scoring histogram structure used by TANDEM to track the statistical nature of the stochastic distribution.
