LHE file is not properly initialized

Asked by Muhammad Danish Aslam on 2020-08-25

You answer related to question #692472 works. I generate events then a file named events_1.txt is produced in results directory. I run this file on my code i got this error "lhe file is not proper initializes thats why not generating events" so i think may be these events are not in lhe format. So I went to work/bin directory and uses ./event2lhe events_1.txt command for the conversion of events in lhe format. But when i run this file on my code I got the same error again. But when I run unweighted_events1.lhe file generated from Madgraph (a package for the generation of events) it works perfectly.
 Suggest me am I right in generating events? If not then what is the correct way to generate events in .lhe format??
I am using calchep_v3.7.5.

Yes, it is  right.

Also see page 23 in https://arxiv.org/pdf/1207.6082.pdf

Other  option is to use event_mixer which  combines several event files
in realize decays.

Also one can use calchep_batch to launch by one command compilation of
several channels, generation events, their mixing and generation of
final lhe file.

Ok,
Now I generate a batch_file for my channel but it gives such error when using ./run_batch batch_file1 command.

danish@danish-Latitude-E7440:~/compiler/analysis/calchep_3.7.5/work/bin$ ./run_batch batch_file1

calchep_batch version 1.45

Processing batch:
Progress information can be found in the html directory.
Simply open the following link in your browser:
file:///home/danish/compiler/analysis/calchep_3.7.5/bin/html/index.html
You can also view textual progress reports in /home/danish/compiler/analysis/calchep_3.7.5/bin/html/index.txt
 and the other .txt files in the html directory.
Events will be stored in the batch_results directory.

Could not find model: 2HDM-I-BSM

Here I inserted 2HDM-I-BSM model manually and then edited it into 2HDM-I-BSM. This model shows in GUI and work properly. Then why this error occurs. Firstly I just keep model file in model directory but after that I have counter checked by putting model files in model directory of main directory of calchep.
