It seems that the various Jupyter Notebooks which use the ipympl library have a problem with the latest versions of the anaconda distribution (starting with python 3.9), and probably with other distribution as well.

Try the following possibilities if you have problem with the graphic and/or the interaction in the Spike Notebooks

1. the team developping jupyter is migrating the notebook to a new technology and Spike is not yet adapted to this new environment. In the meantime, use nbclassic instead of notebook to launch the various notebooks

   jupyter-nbclassic TheNooteBook.ipynb
   

2. The interaction is based on the optionnal ipympl extension, and some people have instabilities in the interaction upgrading ipympl to the 0.9.3 version seems to solve the difficulty:

   pip install ipympl==0.9.3
   

or alternatively conda config --env --add channels conda-forge conda install ipympl=0.9.3 Depending on your set-up (jupyter version) it might work either in jupyter lab, jupyter notebook or jupyter nbclassic, or even all of them.

SPIKE a collaborative development for a FT-spectroscopy processing library.

This is the version 0.99.33 - Octobre 2023

SPIKE allows the processing, the display and the analysis of data-sets obtained from various Fourier-Transform spectroscopies. The name stands for Spectrometry Processing Innovative KErnel.

It allows the processing of 1D and 2D FT spectroscopies, mostly NMR and FTICR-MS, but also Orbitrap, and other to come.

It implements all needed tools for Data analysis (Fourier Transform, Baseline correction, noise reduction, peak-picking, etc...)

To our knowledge, it is the first program freely available allowing the processing, display and analysis of 2D-FT-ICR (Fourier Transform Ion Cyclotron Resonance), as well as Orbitrap time domain data processing.

It is written in python3 currently developed in python 3.11 (python 2.7 has been tested up to version 0.99.10). It is tested in python versions from 3.7 to 3.11.

It is mostly a library for processing, analysis and display of spectral data-sets. The natural interface is either a python program or a jupyter notebook as an interactive front-end.

An additional program, called SPike Interactive (or SpI ) is also developed, it consists in a set of stand alone jupyter Notebooks which allow to use SPIKE process and analyse NMR and MS datasets without any programming knowledge.

It provides simple interactive environment which implement basic analysis can be found in the SpI directory. A part of SpI is also contained in the Interactive directory in the source tree.

It is still in very active development, but also the basis for our research.

Many features are missing, and many other while present, are not fully fixed. However, considering the amount of efforts already present in this code, we decided to make it available. We believe that even in this current development stage, this program might prove useful for certain usages.

Basic presentation of functionalities can be found Here

A complete documentation, with the full API, can be found Here. We try to keep it up to date, but it may lag a little behind the current program state.

Most of the documentation is in the code itself, available directly while programming (try function_name? in jupyter notebook).

Another source of documentation are Notebooks directory. There are two type of Notebooks, fully developed ones, with interactive tools, which can be used as is, and example Notebooks, meant for pedagogic purposes. This is an ongoing effort, and always short of what we'd like to do.

Can be found Here

You might have python installed on your system, however, SPIKE relies on a whole set of scientific libraries which may dont be installed (see Dependencies below). We advise to install a scientific python environment such as Anaconda or Enthough. Then install SPIKE with the following command in the terminal:

pip install spike-py

This will install the latest version on your machine. (be sure to use the pip command which came with the scientific python environment).

If you already have SPIKE installed and want to upgrade to the last version do:

pip install -U spike-py

Thepip instalation is always less recent than the github version, if you need the latest version, you simply instal it in the following way:

• Get the last version on github, using git (prefered)

    git clone https://github.com/spike-project/spike.git
  

• then go to the spike directory and type the following command (new syntax due to changes in development team)

    pip install -e
  

This method allows you to update your Spike distibution from github and always use the latest version by doing

    git pull; git update

in your spike directory.

Alternatively, you can simply download the archive

    wget https://github.com/spike-project/spike/archive/refs/heads/master.zip
    unzip master.zip
cd spike
    pip install -e

Several additional tools may be of interest.

a/ Interactive jupyter notebooks from SpI can be found in the Notebooks directory or on github. You will find there fully developed interactive notebooks allowing data analysis without any knowledge in python programming, as well as examples to starting writing small pyhton programs for specific needs.

First the tool ipympl needs to be installed (it may not be installed along the scientific environment) To install it, simply do (check warning above):

pip install ipympl

Then copy the related NotBooks to a directory by typing in a terminal in this directory.

python -m spike.installSpI

this will copy all the tools, you can safely remove the unneeded one, as the same command will always bring you all the notebooks.

b/ additional plugins are available in the plugins/special directory in the source tree. check on github.

If you want to use them, create a directory called Spike in your HOME directory, and a directory called plugins in this one (hence $HOME/Spike/plugins), and put then there, they will be directly activated. You can also develop your own plugins and put them here.

Note that some plugins or extension require additional libraries (ipympl, MPI, bokeh, mayavi, ...)

The Spike program is distributed under the CeCILL 2.1 FREE SOFTWARE LICENSE AGREEMENT Which is the GPL license adapted to the French law.

It includes the following additional programs/algorithms:

• urQRd L.Chiron and M-A Delsuc (denoising of large harmonic signals) under CeCiLL licence
• PALMA A.Cherni and M-A.Delsuc (Processing of DOSY based on ILT) under CeCiLL licence
• progressbar N.Volpato - under LGPL licence

The SPIKE source is available at https://github.com/spike-project/spike

SPIKE is written in pure Python, and relies on several external libraries:

• matplotlib
• numpy
• scipy
• tables
• pandas

It is compatible and fully tested with python 3.7 and 3.10

SPIKE is originated from the Gifa program, developed by M-A Delsuc and others in FORTRAN 77 since the late eighties, it still shares similarities, such as command names, or internal data organisation.

Gifa was abandoned around 2005, but it actually experienced a revival in 2020 thanks to the " ten years challenge " organised by the ReScience C Journal. You can find an installable and runnable version here: https://github.com/delsuc/Gifa

Gifa has known several mutations, and finally ended as a partial rewrite called NPK. The NPK program is based on some of the original FORTRAN code, wrapped in Java and Python, which allows to control all the program possibilities from the Python level. NPK is purely a computing kernel, with no graphical possibilities, and has been used as a kernel embedded in the commercial program NMRNoteBook, commercialized by NMRTEC.

However, NPK was showing many weaknesses, mostly due to the 32bits organization, and a poor file format. So, when a strong scientific environment became available in Python, a rewrite in pure Python was undertaken. To this initial project, called NPK-V2, many new functionalities were added, and mostly the capability to work in other spectroscopies than NMR.

At some point in 2014, we chose to fork NPK-V2 to SPIKE, and made it public.
