-# MCEGENpiN_radcorr V7f
-This V7f version of the newest MC event generator for exclusive single pion electroproduction allows you to generate a massive statistics for the large invariants' scales. Relatively fast and effective procedures in conjunction with model representations make this program a convenient and reliable choice for data analysis in particle physics.

 ## What's it all about?
 One of the biggest parts of any experiments in physics is data analysis. Hadron physics with [CLAS12 spectrometer](https://www.jlab.org/physics/hall-b/clas12) gets pretty tricky when one should deal with its efficiency. This is where programs like this generator come quite handy. Not only do they allow you to restore the original cross-section, but they also can be used as an instrument for event selection development.
