Detailed Description

convert time of flight to charge to mass ratio

Available PostProcessors:: "404": convert time of flight to charge to mass ratio

converts a time of flight trace of ions to the coresponding mass to charge ratio.

In order to calculate the Mass to Charge ratio one has to provide two known peaks and their Charge to Mass ratio. From this information the rest is calculated.

User definable Parameters:

Processor/%name%/{TofLow|TofLow}
The time of flight range within the histogram to convert to mass. to charge ratio Default is 0|1.

Processor/%name%/{t0}
a time of flight of ion that we choosed. Default is 0.

Processor/%name%/{t1}
another time of flight of ion that we choosed. Default is 0.

Processor/%name%/{MtC0}
mass to charge ratio of t0. Default is 0.

Processor/%name%/{MtC1}
mass to charge ratio of t1. Default is 0.

Processor/%name%/{tb1}
The lower limit for calculating baseline. Default is 0.

Processor/%name%/{tb2}
The upper limit for calculating baseline. Default is 0.

Processor/%name%/{NbrBins}
number of bins in converted histogram. Default is 0.
