model sm_v4.tgz not found

Asked by Angela on 2018-05-11

when I do
import model_v4 sm -modelname
I get an error message:

MG5_aMC>import model_v4 sm -modelname

INFO: download model from ./sm_v4.tgz to the following directory: /home/gs922050/hep_tools/madgraph/MG5_aMC_v2_6_2/models
Command "import model_v4 sm -modelname" interrupted with error:
Exception : ['./wget', './sm_v4.tgz', '--output-document=tmp.tgz'] fails with no such file or directory

I dont find the file sm_v4.tgz anywhere. There is already a "sm" file in models directory.

Hi,

The online model database was corrupted for a couple of model.
It should work now.

Note that you should not use the MadGraph4 model but if you want to compare with those old model.
Those model are basically not supported anymore and are less efficient compare to the UFO model.
Also many functionality of the code are not compatible with this type of model.

So I would suggest to do
import model sm instead (this correspond to the model "sm" in your models directory)
doing "import model_v4 sm" will download a directory sm_v4 in your models directory)

Cheers,

Olivier
