[Comphep-common] Events to produce of LHAEF format

[Ijaz Ahmed]

Dear  Lev,
Actually after all my struggle, i am writing this email on this list.

  At the moment, simply i want to generate W+j1 process (later on W+j3,j3), whose i generate process.dat file and then on my terminal symbolic calculation command run, which could not produce n_comphep.exe file, it always ends with error and no, file like session.dat and batch.dat are produced, which are necessary for numerical calculation to produce finally events. It compiled 100% and qt the end it printed error as you can see below:

So my problems is at the symbolic stage. For instance i give command and my process.dat file is there,
*******************.
/symb_batch.pl mp 4

Error during link of n_comphep! See symb_batch.log
ERROR: make error

*** n_comphep creation details have been written to symb_batch.log (make stdout/stderr)****

***********************************
What i should do. Please give me reply, i struggled myself a lot.
thanks
ijaz

      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.
