| + | ==== Single Match per Query Filter ==== | ||
| + | |||
| + | This filter keep only ONE match per query. The best match is kept; as best is defined as the one with highest score. If there is equality the match leading to the master Protein with highest score will be chosen. If there is still equality the first peptide encountered is arbitrary chosen.\\ | ||

| + | === Example 1 === | ||
| + | In this example the query n°20 has 4 matches leading to protein (AGVLAEVR, LNIPTTR, NLLADLR, LDICQLR) (**Fig 1**). As the first (AGVLAEVR) have the higher score (23.15, **Fig 2**) all the others will be mark as ambiguous by the filter.\\ | ||

| + | |||
| + | === Example 2 === | ||
| + | The query n°1060 has 2 matches leading to proteins (LLIYGA**ST**R & LLIYGA**TS**R). Due to T & S swapping the two matches has the same score (35.14). As the second one (LLIYGA**TS**R) leads to a protein with the higher score (212 opposed to 127) the first one will be mark as ambiguous. | ||

| + | **Nota** : in that example, apply the Score & Rank filter with parameters to only kept rank 1 peptides would have lead to mark the second one as ambiguous, in contrary of the Single Match per Query Filter | ||
