Magnify

A magnifier to investigate raw and deconvoluted waveforms.

Preprocess

./preprocess.sh /path/to/your/magnify.root

This is a wrapper for merging magnify histograms from all APAs. See more detailed description through "./preprocess.sh -h".

Usage

cd scripts/
root -l loadClasses.C 'Magnify.C("path/to/rootfile")'
# or
root -l loadClasses.C 'Magnify.C("path/to/rootfile", <threshold>, "<frame>", <rebin>)'

The second argument is the default threshold for showing a box.

The third, optional argument names which output from the signal processing to display. Likely names are:

• decon produced by the Wire Cell prototype (default).
• wiener produced by the Wire Cell toolkit, used to define ROI or "hits".
• gauss produced by the Wire Cell toolkit, used for charge measurement.

The call to ROOT can be be called somewhat more easily via a shell script wrapper. It assumes to stay in the source directory:

/path/to/magnify/magnify.sh /path/to/wcp-rootfile.root
# or
/path/to/magnify/magnify.sh /path/to/wct-rootfile.root 500 gauss 4

Example files

An example ROOT file of waveforms can be found at twister:/home/wgu/Event27.root

If one omits the file name, a dialog will open to let user select the file:

cd scripts/
root -l loadClasses.C Magnify.C

RMS & FFT noise analysis (batch)

Compute per-channel noise RMS and frequency spectra for one or more Magnify files:

./scripts/run_rms_analysis.sh input_data/magnify-run.root
# Produces: input_data/magnify-run.root.rms.root

The cache file contains per-plane RMS TTrees (rms_u/v/w) and FFT TH2Fs (fft_u/v/w, channel × frequency in MHz). It is loaded automatically by the viewer when you click RMS Analysis in the control bar. See docs/RMS_FFT.md for the full workflow and panel description.

(Experimental feature) Channel Scan

./channelscan.sh path/to/rootfile

This is a wrapper for looping over channels where the channel list can be predefined in the bad tree or a text file.

See detailed usage via ./channelscan.sh -h.
