``` git clone https://github.com/E1039-Collaboration/seaquest-analysis.git ```

run the Fun4All shielding macro into the local gpvm machine:

``` cd <path-to-/seaquest-analysis/E1039Shielding> root -l Fun4E1039Shielding.C ``` Several root files are generated. The 'trk_eval.root' contains the information from the evaluator [TrkEval]. You may open that file and check the contents.

``` $root -l trk_eval.root root [0] Attaching file trk_eval.root as _file0... root [1] .ls TFile** trk_eval.root TFile* trk_eval.root KEY: TTree T;1 TrkEval ```

analysis

This root file 'trk_eval.root' needs to be attached in the macro for analysis. The analysis macro ana.C is for acceptance vs hole size study and the macro loop_ana.C is for acceptance vs dimuon mass study. You may test it using the example data from the trk_eval.root. ``` root -l root [0] .L ana.C root [1] drawRelAcc() root [2] drawAccPhi() ```

``` root -l root [0] .L loop_ana.C root [1] drawAccMass() ```

run the Fun4All shielding macro in Fermilab grid (the switch info can be found in gridrun.sh and gridsub.sh):

``` ./gridsub.sh opening 1 100 1000 1 ```

Check the status and output root file

``` jobsub_q –user=<your-user-id> cd /pnfs/e906/persistent/users/<your-user-id>/E1039Shielding

```

Collect all the root files in a single root file

hadd <output-filename>.root /pnfs/e906/persistent/users/<your-user-id>/E1039Shielding/<name-of-your-output-file>/*/out/trk_eval.root
