[Comphep-common] Events to produce of LHAEF format

[Lev Dudko]

      Dear Ijaz,
  You can follow standard instructions how to generate events in CompHEP
(tutorials, publications, manual). Please, start from the simple process
and get the result, then increase the complexity. 
   NNPDF is not implemented as internal structure function in CompHEP
and you need to use standard interface to LHAPDF package where this
function has implemented. 
      Best regards,
         Lev

In W+,j3,j3 channel, there are many subprocess and to compile them it takes a long time. what is short way, i have only one machine to do that.

I do produce process.dat from GUI. but still wanat to start Numerical calculation, but symbolic calculation is not going to complete, specially from GUI, c-compile is completed with error.
