Description of contents:
    
    - In the molecules_reactivity_network.csv file there are all the extracted and organized 
    information of all the species in the above mentioned folder (i.e. species).
    The csv columns are: 
    species (the codification name), 
    Name (chemical name, if present), 
    Formula (number of atoms per element), 
    Mass (molecular mass, in a.u.), 
    N_atoms (total numer of atom inside the species), 
    Charge (electric charge), 
    Detected (detected in space?), 
    SpinMultiplicity (electronic spin multiplicity), 
    Energy_Eh (electronic energy in Eh, 
    computed at CCSD(T)/aug-cc-pVTZ//M06-2X/cc-pVTZ), 
    ZPE_Eh (Harmonic zero-point-energy in Eh, computed at M06-2X/cc-pVTZ)
    
    - The following files are Reaction Networks, the file format used for these file
     is reported in details at the bottom of this ReadMe.
        -- Gretobape_pre_endo_cleaning.dat  is the original Reaction Networks before cleaning process

System requirements: The file format of the reaction network files.

    The format and columns of the kida.uva file is the following (as for kida networks downloaded from kida):
    
    Format: 3(a10 1x) 1x 5(a10 1x) 1x 3(e10.3 1x) i5 1x i5 1x a4 1x i2 1x i6 1x i6 1x i2 1x i5 1x i2 1x i1
    Reactants   Products  alpha  beta  gamma  F g Type_of_uncertainty   itype    Trange   Formula    Number     Number_of_(alpha, beta, gamma)      Info

    Columns:
    - "alpha, beta, gamma " are the parameters to compute the rate coefficients. The formula depends on the type of reaction. See http:// kida.obs.u-bordeaux1.fr/help
    
    - "F" is the uncertainty factor on the rate coefficient (See http://kida.obs.u-bordeaux1.fr/help)
    
    - "g" is the temperature dependence of this uncertainty factor (See http://kida.obs.u-bordeaux1.fr/help) 
    Type of uncertainty : lognormal (logn) , normal (norm) , loguniform (logu) , uniform (unif)
    
    - "Itype" is the type of reaction : See http:// kida.obs.u-bordeaux1.fr/help

    - "Trange" is the range of temperatures the rate coefficient is valid. 
    We do not recommend to make extrapolations outside this range. When we do not have information on Trange, default values are used: -9999,9999.

    - "Formula" is a number that referes to the formula needed to compute the rate coefficient of the reaction. 
    1: Cosmic-ray ionization (direct and undirect)
    2: Photo-dissociation (Draine)
    3: Kooij 
    4: ionpol1 
    5: ionpol2 
    6: Troe fall-off
    Correspondances of the names to the mathematical expression can be found at this address: http://kida.obs.u-bordeaux1.fr/help
    Note that for photorates, the type of the UV field is contained in the name fo the formula. For example, Draine means standard interstellar radiation field cf Draine (1978, ApJS, 36,595 ). 
    
    - "Number" is the number of the reaction in the downloaded network.
    
    - "Number of (alpha, beta, gamma)" is the number of (alpha, beta, gamma) in the downloaded network when several values are present in KIDA. 
    When a user selects a range of temperature and that several rate coefficients in KIDA can be in agreement with his search, all data will be included in the network. 
    We then expect the user to choose one of the values. If the reactions are particularly important, we advise the user to contact KIDA to get advises. 
    These reactions that are present more than once in the network are listed below.
    
    - "Info" is information on reaction, like literature reference or comments
