ramanfitter 0.0.2

A Raman peak finder and model fitter

ramanfitter

This package seeks to provide and easy and efficient matter for fitting Raman data with Lorentzian, Gaussian, or Voigt models.

Developed by John Ferrier, NEU Physics (c) 2022

Quickstart Example

For a simple run,

import os
import numpy as np
from ramanfitter import RamanFitter

filename    = os.path.join( 'path', 'to', 'data.csv' )      # Get File
data        = np.genfromtxt( filename, delimiter = ',' )    # Open File

x           = data[ :, 0 ]                                  # Parse x-values
y           = data[ :, 1 ]                                  # Parse y-values

RF          = RamanFitter( x = x, y = y, autorun = True )   # Run Fitter automatically

components  = RF.comps                                      # Returns a dictionary of each curve plot
curveParams = RF.params                                     # Returns a dictionary of the parameters of each Lorentzian, Gaussian, or Voigt curve
bestFitLine = RF.fit_line                                   # Returns the plot data of the model

For more control over parameters

data        = np.genfromtxt( filename, delimiter = ',' )    # Open File

x           = data[ :, 0 ]                                  # Parse x-values
y           = data[ :, 1 ]                                  # Parse y-values

RF          = RamanFitter( x = x, y = y, autorun = False )  # Run Fitter automatically
