Search Settings dialog box parameters
The following table describes the search parameters in the Search Settings dialog box.
|
Parameter |
Definition |
|---|---|
|
Database for Searching |
Specifies the UniProt XML file containing protein information, such as sequence, accession number, and PTMs. |
|
Run Intact Mass Search |
When enabled, specifies the search will match fragment ion masses against theoretical candidate proteoform masses in the database. |
|
Run Fragmentation Search |
When enabled, specifies the search will match fragment ion masses against theoretical candidate proteoform masses in the database. |
|
Run Delta M Mode |
When enabled, specifies the search will use the mass difference between the theoretical candidate mass and the observed precursor as a potential PTM. |
|
Run Subsequence Search |
When enabled, specifies the search will consider smaller subsequences of a proteoform (for example, protein truncation). |
|
Scan Filter Override |
Specifies the type of fragmentation to search against. |
|
Precursor Target Tolerance |
Specifies the window around the isolated precursor target. |
|
Precursor Tolerance |
Specifies the window around the experimental mass from which to pull candidate proteoforms for the fragmentation search. |
|
Subsequence Search Precursor Tolerance |
Specifies the window around the experimental mass from which to pull candidate proteoforms for the subsequence search. |
|
Retention Time Tolerance |
Specifies the time tolerance for associating fragmentation data with precursors. |
|
Maximum Number of PTMs per Isoform |
Specifies the maximum number of PTMs that will be considered for candidate expansion. |
|
Maximum Number of PTMs per Proteoform |
Specifies the maximum number of PTMs that will be considered for any single proteoform. |
|
Maximum Number of SNPs per Isoform |
Specifies the maximum number of SNPs that will be considered for candidate expansion. |
|
Maximum Mass to Search |
Specifies the maximum mass of a protein that will be included in candidate expansion. |
|
Use in Memory Search |
When enabled, specifies that all candidate proteoforms will be loaded into memory. |
|
THRASH Window Size |
Specifies the isotopic distribution window size. |
