Grid Downloads

Please note that grids should now be downloaded from the ploughshare website from the grid download page.

However, should you really, really want to download the older, unsupported version of the grid files, you can access the old downloads page.

Code Download

Various code for download is available:

  • You can download the latest version (1.6.22) of the standard APPLgrid convolution code here .
  • If you wish to use arbitrary factorisation scale variation, you will need to have hoppet installed first, which you can download from here .
  • There are some simple examples which you can download from here . These examples requires that you have LHAPDF installed which you can find here .
  • In addition, APPLgrid uses root files for storage, although not internally, so you should also install root which you can find here .

Calculation Code

If you wish to generate your own grids, we currently have NLOjet++ available for jet production at NLO and MCFM for most other processes.

  • For NLOjet++ we have our own custom version 4.0.1 which can be downloaded from here .
    This requires the nlojet pdf module that you can download from here .
    The user module can be downloaded from here

  • For MCFM, you should download the standard version of MCFM (6.7 or later). To link with applgrid, before installing MCFM, you should download and install the mcfm-bridge code, which you install with the usual ./configure ; make ; make install etc.

    After running this you will need to patch the standard installation using the patch file which you should untar in the MCFM base directory and then remove the file
       src/User/gridwrap.f 
    
    then just build using make. To link with applgrid, before running make, you should set the LDFLAGS enviroment variable to the output from
       mcfm-bridge --ldflags
    
    NB: you should not use the standard install script that comes with MCFM.
Other interfaces are being developed and will be released when available.
