SiSetProcessingOptions | R Documentation |
SiSetProcessingOptions
sets processing options for each spectrum type.
SiSetProcessingOptions(option, value, specType)
option |
Option to set (see below for a list of valid option strings). |
value |
Value to set the for the given option. |
specType |
Spectrum type index. -1 is a wildcard for all spectrum types. |
Options:
Name | Description | Default value |
MassCalibMode | Mass calibration mode in use (see MassCalibrate ). | 0 |
MassCalibParamn | Mass calibration parameters n = 1..number of calibration parameters for the given mass calibration mode. | c(1000, 0) |
FullScale | Full digitizing range of the ADC in the same units as the spectra to be analyzed (typically mV). | 500 |
NbrBits | ADC resolution (8 for AP240, 14 for ADQ114 etc.). | 8 |
SampleInterval | Sample interval in ns. | 1 |
PreampGain | Gain of external preamp. | 1 |
PreSamples | Number of samples before a threshold crosser taken into account. | 0 |
PostSamples | Number of samples after a negative threshold crosser taken into account. | 0 |
BaselineAndThresholdFromData | If >0 the baseline and threshold
values will be determined based on NbrStdDevs for every processed
spectrum. If >1.5 baseline noise is determined from a fit to a histogram of
all data (instead of from the standard deviation of all data). This makes the
noise determination more robust when real peaks are present in the spectrum. | 0 |
NbrStdDevs | Number of standard deviations of baseline noise that
defines the threshold. Only relevant if BaselineAndThresholdFromData>0 . | 6 |
Baseline | Baseline value used for calculation of intensities. Has
no meaning if BaselineAndThresholdFromData>0 . | 5 |
Threshold | Threshold value used for calculation of intensities.
Has no meaning if BaselineAndThresholdFromData!=0 . | 8 |
NegativeSignal | Indicates peak polarity with respect to the baseline. | 0 (=FALSE) |
BaselineAndThresholdInCodes | Indicates whether the values in Baseline
and Threshold are interpreted as ADC codes or mV. | 1 (=TRUE) |
