analysis code to reconstruct and analyze track/clusters from CYGNUS camera

Checkout instructions:

Convert the H5 files in ROOT files with TH2D

This could be avoided reading directly the H5 files, but for now it is like this... See instructions in:

https://github.com/CYGNUS-RD/hdf2root

The usual name of the runs after the conversion is histogram_Run00494.root or histograms_Run01515.root if it was already a root file.

Updated HOW-TO-RUN

Running the analysis code:

python3 reconstruction.py configFile.txt --pdir plots --max-entries X -jX

• configFile.txt is the configuration file with all the settings.
• pdir is the directory where the plots will be saved.
• max-entries is the number of images you want to analyse.
• j is the number of cores you want to use.

Prerequisite to run:

• Python 2.X (Stable version) or Python 3.X
• Root 6.X

Python libraries:

• cycler==0.10.0
• decorator==4.4.0
• imageio==2.6.1
• joblib==0.14.0
• kiwisolver==1.1.0
• matplotlib==3.1.1
• networkx==2.4
• numpy==1.17.3
• Pillow==6.2.0
• pyparsing==2.4.2
• python-dateutil==2.8.0
• PyWavelets==1.1.0
• root-numpy==4.8.0
• scikit-image==0.16.1
• scikit-learn==0.21.3
• scipy==1.3.1
• six==1.12.0

Example

Download the code from github:

git clone [email protected]:CYGNUS-RD/analysis.git or git clone https://github.com/CYGNUS-RD/analysis.git

cd analysis

Get a file for a specific run taken with the DAQ (eg. run 2113):

wget https://swift.cloud.infn.it:8080/v1/AUTH_1e60fe39fba04701aa5ffc0b97871ed8/Cygnus/Data/LAB/histograms_Run02113.root

Change the run number in the config file (Line 34)

https://github.com/CYGNUS-RD/analysis/blob/fng_18/configFile.txt#L34

emacs -nw configFile.txt

Then run the code on all the events

python reconstruction.py configFile.txt

If your computer has X cores

(check on linux with cat /proc/cpuinfo | awk '/^processor/{print $3}’)

You can speed up the processing by parallelizing it:

python reconstruction.py configFile.txt -j X

You can now look at the output ROOT file with a tree containing 1 event/image with:

root -l reco_run02113_3D.root
