Simulation of Cr3+ spectra

I am unable to simulate the EPR spectra, even i have got all the values required from the papers.
I an new to EasySpin and have tried to use ginger and pepper also confused of all different examples
Can any one give some basic code, i just want to check line broadening and my Cr3+ spectra which has 5 peaks and quite similar to the spectra found in the below reference
DOI: 10.1007/BF00419139
Thankyou
Vijay

Vijay, if you go to easyspin.org -> Documentation -> Examples, you'll find some sample scripts that should help you get started.

Hi Stefan
I tried harder and able to generate the spectra but not able to give the perfect strain so that i can match the intensities and broadening of the spectrum,
As given in documentation i can change either g/A strain or D/E strain
The problem is by giving any strain i am able to change the intensities but at the same time I am getting the broadening of peaks which i don't want.
I did doping studies and with the increase of doping i am seeing there is a peak broadening (PP width) and i want to reflect that in terms of strain.
You can have a look of my coding and Experimental spectra
Thankyou

Hvae you tried to use HStrain?
