Detailed Description

vsmq format file writer

This writer converts data from diana to 'vsmq' format. It produces compressed data files in vsmq format and an header file for each different input run. This writer is able to detect (and skip) possible muon events from Apollo data, but unless it is used in conjunction with MRawDataFilter (KeepMuonVeto=false,SkipEvents=true), the number of events per file will not match the one requested in config file. Not all informations contained in the header file are meaningful. The following quantities can be trusted:

• Number of points per event
• event duration in ms
• ADC range
• Start date and time
• Stop date and time

• Config example:

     writer MQinoRawDataWriter
     verbosity = debug
     enable = true
     OutputDir = ../data
     EvPoints = 512
     PreTriggerPoints = 128
     Differential = true
     ForceInputType = NO
     ForceDetector = NO
     OutputFilePrefix = test_
     OutputFilesList = test.list
     Description = 
     WriteFilesList = true
     endmod
     

• Parameters:
  • EvPoints [int = 512]: number of points per event
  • PreTriggerPoints [int 128]: number of pre-trigger points
  • Differental [bool = true]: select between 'as is' and differentiated output (_d or not)
  • ForceInputType [string = NO]: In principle input data type (Apollo or VXI) can be determined automatically from QRunData, but this is not true for old Apollo data. This option allows to specify the intput type by hand. Valid values for this option are:
    • Apollo (or apollo): 18 bit data from apollo daq
    • VXI (or vxi): 16 bit data from VXI daq
    • Any other string (including NO): input type will be determined automatically
  • ForceDetector [string = NO]: In principle detector identifier (needed to select the correct Apollo ADC calibration coefficients) can be determined automatically from QRunData, but this is not true for old Apollo data. This option allows to specify the detector identifier by hand. Valid values for this option are:
    • DN_CUORICINO: Cuoricino detector
    • DN_HALLC: Hall C detector
    • Any other string (including NO): detector id will be determined automatically Note that this option only makes sense if input data is from Apollo DAQ. In case of VXI input data there is no need to know scaling coefficients.

Member Function Documentation

void MQinoRawDataWriter::WriteFile

(

)

[private]

write current events to file

Parameters:

fileName

name of file to be written

std::string MQinoRawDataWriter::GetTimeString	(	const time_t &	time,
		const std::string &	format
	)			[private]

utility function to convert from time_t to string

Parameters:

	time	value to be converted
	format	date format as specified in strftime()

Returns:

string filled with formatted date or "NOT_DETECTED" if time is 0

QVector MQinoRawDataWriter::Scale	(	const QVector &	data,
		const int	channel,
		const size_t	first,
		const size_t	last
	)			[private]

scale from PXI to VXI adc units

Parameters:

	data	input vector to be scaled
	channel	logica channel the data belongs to. This information is needed to choose the corect calibration coefficients
	first	first sample to be scaled (included)
	last	last sample to be scaled (excluded)

Returns:

QVector containing scaled data

void MQinoRawDataWriter::DumpStatistics

(

)

[private]

dump statistics about events that have been modified due to to incompatible values found in input data (negative voltage, values exceeding max ADC input and so on).

This function also reset the statistics counters
