Comment 1 for bug 1876573

Hi,

You will find the patch (and download of the nightly build) here:
https://bazaar.launchpad.net/~mg5core1/mg5amcnlo/2.7.3/revision/306

For editting the madspin card, the only option (but for the decay mode and the spinmode)
is to use the "edit" command
for example:

edit madspin_card --replace_line='set ms_dir' --after_line=banner set ms_dir TEST_XX
(the after_line argument is only use if they are no line starting by "set ms_dir" in your file)

Therefore your script can be:

generate p p > t t~
launch
madspin=full
set nevents 100000
edit madspin_card --replace_line='set ms_dir' --after_line=banner set ms_dir TEST_XX
decay t > w+ b, w+ > l+ vl
decay t~ > w- b~, w- > l- vl~

Note that you can not use the same TEST_XX for the three mode of madspin.

Cheers,

Olivier
