Hyperspectral imaging (HSI) processing and analysis platform (user interface, UI)
CRIKit2: Hyperspectral imaging toolkit
CRIKit2, formerly the Coherent Raman Imaging toolKit, is a hyperspectral imaging (HSI) platform. It is composed of command line tools, interactive tools, and a user interface.
Github Repository: https://github.com/CCampJr/CRIkit2 Docs Website: Coming Soon…
Note: Help Documentation available via the Help header within the CRIkit2 GUI (only for git installs, not pip)
- Dark subtraction
- Denoising via SVD
Coherent Raman-Specific Processing:
- Kramers-Kronig phase retrieval
- Phase- and scale-error correction
- SVD automated selection tools
- Analysis toolkit (separate UI)
- Interactive Raman database
- Much more
- Major bug fix in 0.2.1 (Issue #84)
Note: These are the developmental system specs. Older versions of certain packages may work.
- python >= 3.4 - Tested with 3.4.4, 3.5.2, 3.6.1, 3.7.2
- matplotlib (1.*, 2.*, 3.*)
- LazyHDF5 >= 0.2.2
- Requires H5Py (>= 2.6)
- SciPlot-PyQt >= 0.2.2
- Requires Matplotlib (v1.*, 2.*, or 3.*)
- Sphinx (optional)
IMPORTANT: For Python 3.4
You will need to manually install PyQt5 and Qt5 or get it through a distribution:
For Python 3.5, installation through pip available
pip3 install pyqt5
Windows 10 with High-Resolution Monitors
The GUI may appear squashed with small font. There is a work-around described at https://github.com/CCampJr/CRIkit2/issues/79
There is a bug in PyQt 5.7.* that will prevent SciPlot’s tables from showing the individual plot entries (see https://www.riverbankcomputing.com/pipermail/pyqt/2017-January/038483.html). Apparently, this will be fixed in 5.7.2.
- As WinPython 184.108.40.206Qt5 and 220.127.116.11Qt5 use PyQt 5.7.*, it is advised to use WinPython 18.104.22.168Qt5 or 22.214.171.124Qt5 until the matter is sorted out.
- Alternatively, one can uninstall pyqt5.7.* and force an install of <= 5.6.*.
It is advisable to clone CRIkit2 via git (https://git-scm.com/) and install in a developmental mode via pip or conda as this will enable you to easily (relatively) update your copy of CRIkit2 as new functionality is pushed.
Note If you choose to clone an updatable copy of CRIkit2, do not clone to a directory within your Python installation. Rather, create a new directory elsewhere. That way if you update your Python distribution, you won’t lose your copy of CRIkit2.
Option 1: Dynamic, Updatable Clone of CRIkit2
# Note: in Windows, commands will be followed by .exe # Note: On multi-python systems, you should probably append a 3 to end # the end of commands, e.g., pip is pip3, python is python3 # Assume the new directory will be CRIkit2 (it can be anything) # Clone from github git clone https://github.com/CCampJr/crikit2.git CRIkit2 # Within install directory pip install -e . # To update installation, from within the CRIkit2 directory git pull # If you receive an error trying to update via git pull # See https://github.com/CCampJr/CRIkit2/issues/82
Option 2: Static Copy
The static copy will copy the CRIkit2 install into your Python distribution and will not be updatable without re-installing CRIkit2
# Note: in Windows, commands will be followed by .exe # Note: On multi-python systems, you should probably append a 3 to end # the end of commands, e.g., pip is pip3, python is python3 # Assume the new directory will be CRIkit2 (it can be anything) # Clone from github git clone https://github.com/CCampJr/crikit2.git CRIkit2 # Within install directory pip install . # You can now delete the source files you downloaded if so desired # To update installation, from within the CRIkit2 directory git pull pip install .
Option 3: Installation via pip
pip install CRIkit2
(Re-) Building Documentation
A pre-built version of the documentation is included with the installation; thus, this step should not be necessary unless you are making modifications to the software.
The documentation is accessible from within CRIkit2 under the Help header. It is displayed in a web browser.
# From within the CRIkit2 directory (not crikit) cd docs # Clean out old docs (optional) make clean # On Windows make.bat clean # Build API w/o pyuic5-generated files # Windows add .exe sphinx-apidoc -f -o ./source/ ../ ../crikit/ui/qt_* ../crikit/ui/*_rc* ../crikit/ui/old/** ../setup.py make html # On Windows make.bat html
Starting the CRIkit2 UI
python3 -m crikit # or python -m crikit
Known Operational Nuances
- The SVD visualization tool uses a complex-valued SVD for complex values; thus, there are a few
things to avoid
- If your spectra are PURELY IMAGINARY, convert them to PURELY REAL
- If your real and imaginary parts of your spectra are IDENTICAL, then consider using just the real or imaginary portion
- NOTE: this does not affect the accuracy or performance of SVD or the returned results, but you will see unexpected visualizations of the spatial and spectral components.
