Making a scan matrix file

The output of a scan matrix file is trigged by the -p flag in RawTools.

Windows

>RawTools.exe -f [path to raw file to be analyzed] -p

Linux

$mono RawTools.exe -f [path to raw file to be analyzed] -p

MacOS

$mono RawTools.exe -f [path to raw file to be analyzed] -p


Data output

The output file should resemble the image below when opened in Excel. The image is truncated due to size.

The data can be interpreted as described below. By default, RawTools outputs scan data for all triggered MS2 scans.

Name Description
MS3ScanNumber The index number of the MS3 scan associated with the listed MS2 scan (if an MS3 method was used).
MS2ScanNumber The index number of the MS2 scan.
MS1ScanNumber The index number of the MS1 scan that the MS2 scan was triggered from.
QuantScanRetTime The retention time in minutes of the current MS2 or MS3 scan (if an MS3 method was used).
ParentScanRetTime The retention time in minutes of the MS1 scan that triggered the current MS2 scan.
Duty Cycle The amount of time in seconds required to complete the duty cycle where the current MS2 scan was acquired.
MS2ScansPerCycle The number of MS2 scans triggered by the MS1 scan where the current MS2 was triggered from.
ParentIonMass The m/z of the parent mass for the current MS2 scan.
MonoisotopicMass The monoisotopic mass of the parent ion for the current MS2 scan.
PrecursorCharge The charge state of the parent ion for the current MS2 scan.
ParentPeakFound A TRUE or FALSE indicator of whether a peak for the parent mass was found by RawTools when looking in prior and following MS1 scans.
PeakFirstScan The first MS1 scan index where the parent mass for the current MS2 scan is observed.
PeakMaxScan The MS1 scan index where the maximum parent ion peak intensity for the current MS2 scan was observed.
PeakLastScan The last MS1 scan index where the parent mass for the current MS2 scan is observed.
BaseLinePeakWidth(s) The peak width in seconds at baseline for the parent mass corresponding to the current MS2 scan.
PeakParentScanIntensity The intensity of the parent ion in the MS1 scan where it triggered the MS2 event.
PeakMaxIntensity The max intensity of the parent ion across the MS1 scans where it is observed.
MS1IonInjectionTime The time in milliseconds used for ion injection for the MS1 scan corresponding to triggering the current MS2 scan.
MS2IonInjectionTime The time in milliseconds used for ion injection for the MS2 scan.
MS3IonInjectionTime The time in milliseconds used for ion injection for the MS3 scan corresponding to the current MS2 scan.
HCDEnergy If HCD was used, this value corresponds to the NCE setting used for the current MS2 scan.
MS1MedianIntensity Median intensity of all ions observed in the MS1 scan that triggered the current MS2 event.
MS2MedianIntensity Median intensity of all ions observed in the current MS2 scan.

The parse command can also be used in combination with the '-u' flag to add precursor area quantification to the output.

Windows

>RawTools.exe -f [path to raw file to be analyzed] -pu

Linux

$mono RawTools.exe -f [path to raw file to be analyzed] -pu

MacOS

$mono RawTools.exe -f [path to raw file to be analyzed] -pu


Using the -u flag will trigger the addition of a new column in addition to those above.

Name Description
ParentPeakArea The calculated area-under-the-curve of the parent peak.
