ERROR in strfun

I have tested it for SM
===================
Model: Standard Model(CKM=1)
Model changed: False
Gauge: Feynman
Process: A,e->W-,ne
pdf2: ISR & Beamstrahlung
pdf1: Laser photons

Bunch x+y sizes (nm): 560
Bunch length (mm): 0.4
Number of particles: 2E+10
=================

It seems, no problem with structure functions.
Have you success with batch in SM?

Best

Dear Yuchen,

there are two problems in your batch:

1. The scan statement is not correct:

Scan parameter: ML
etc

should be replaced with
Run parameter:ML
etc

please read manual on how to correctly use the option

2.
Scan begin: 2050
the initial value does not make sense since the collider energy is below the particle mass

These problems, however does not explain the problem with Structure function error you have.
We can not reproduce it.

To reproduce and solve your problem we need to know
1. The calchep version you are running
2. The model you are using

Looking forward to hear from you

Thank you
Sasha Belyaev

Dear Pukhov and Belyaev,

Thank you for your answers.
I tried the test batch which is offerd by Pukhov, and it worked well.
I also modify the scan statement:
================================
Model: EIM
Model changed: True
Gauge: unitary
Process:e-,a->L--,W+

pdf1: None
pdf2: Laser photons
p1: 500
p2: 500

Parameter: clam=5000
Run parameter: ML
Run begin: 500
Run step size: 10
Run steps: 10

Number of events (per run step): 1000
Filename: ea_LW
Max number of cpus: 12
nSess_1: 5
nCalls_1: 10000
nSess_2: 5
nCalls_2: 10000
================================
The error shows
"ERROR in strfun
Error in calculation of cross section for e-,a->W+,L--
Please have a look at cs.o and cs.out in Processes/m4/unitary/p1/single.
Killing all jobs and quitting."
================================

I think it may be some wrong in my model files.
I was also struck by the question of whether I can trust the results obtained by the Interactive mode.
I can run with this model well in the Interactive mode.

My calchep version is CalcHEP 3.6.28. The model I am using is a new model output by feynrules .

Thank you
Yuchen Guo

Dear Yuchen,

as I said in my previous message,

To reproduce and solve your problem we need to know
1. The calchep version you are running
2. The model you are using

as you have correctly mentioned, the problem looks like is related to your model files.
Please send them to us.

Yes, sure, you can trust interactive mode

Dear Experts,

Sorry for late responses.
I revised my model files, it can generate events, but still report some errors:
(My calchep version is CalcHEP 3.6.28)

We need the model from you

Could you send me your model, please, so I can reproduce your problem?
Please send the model to <email address hidden>

We did not receive anything from you
do you still have the problem?
