## PTR-TOF-MS raw data from a rhdf5 file

### Description

A ptrRaw object contains PTR-TOF-MS raw data from one rhdf5 file. It is created with the `readRaw` function.

### Slots

`name`

  the file name

`rawM`

  the raw intensities matrix

`mz`

  array of the m/z axis

`time`

  numeric vector of acquisition time (in seconds)

`calibMzToTof`

  function to convert m/z to Tof

`calibToftoMz`

  function to convert tof to m/z

`calibCoef`

  calibration coefficients (a,b) such that: mz= ((tof-b)/a)^2 for each calibration period

`indexTimeCalib`

  index time of each calibration period

`calibMassRef`

  the reference masses used for the calibration

`calibError`

  the shift error in ppm at the reference masses

`calibSpectr`

  the spectrum of calibration reference masses

`peakShape`

  average normalized peak shape of the calibration peak

`ptrTransmisison`

  matrix with transmission values

`prtReaction`

  a list containing PTR reaction information: drift temperature, pressure and voltage

`date`

  acquisition date and hour
