Software for parsing/analyzing fADC125-generated root files.
A complete ROOT install is required.
cd src
make
sudo make install
This will compile the fadc executable and its dependencies and install them in your system
This utility is accessed easily through the use of the fadc command. It uses this syntax:
fadc [...OPTIONS] COMMAND CHANNEL ROOT_FILE
For example:
fadc -p average view 13 220.root
This uses the average peak detection method to view the peak on channel 13 in the file 220.root.
Available Commands:
view: displays waveforms, including detected peak windows if a peak detection method is specified.analyze: If peak detection method is specified, prints computed characteristics of detected peaks to standard out.Available Options:
-p --peakmethod: Chooses a peak detection method, one of average, fractional or constfrac. The average method computes the average value of the waveform, and defines the peak as the first region where the waveform goes above and then below the average. WARNING: this method will find a peak in ever ywaveform. The fractional method looks for successive significant increases in the value of the waveform. constfrac is a hybrid approach, and is typically the best to use.-o --outfile: Sets an output file for text generated by fadc.-y, --yrange: Sets the maximum of the y axis in the plots displayed by the view command.
<<<<<<< HEAD-s-,--samples`: Set the number of samples used to calculate a waveform baseline for the constant fraction peak detection method.-t, --threshold: Set the fractional threshold used to identify peaks in the fractional and constfrac methods. Should be a value between 0 and 1, with higher values requiring peaks to be higher/steeper to appear in the command output.channel may be an integer fADC125 channel number (0-24), or all to display all the waveforms in the file regardless of channel.
ROOT_FILE is a data file from the fADC, converted to .root format.
