| 19 | 9 | Andrew Sutton | |
| 20 | 8 | Andrew Sutton | These run using the FTBF wire chamber daq which can be accessed from one of the FTBF machines |
| 21 | 8 | Andrew Sutton | <pre> |
| 22 | 8 | Andrew Sutton | ssh -XY ftbf_user@ftbf-cr-02.fnal.gov |
| 23 | 8 | Andrew Sutton | cd /home/tmp_forJason/EDIT2018/MWPC-MCenter (location subject to change) |
| 24 | 8 | Andrew Sutton | ./daq-mcenter_<target || upstream>.py |
| 25 | 8 | Andrew Sutton | data is saved to /home/tmp_forJason/EDIT2018/MWPC-MCenter/data |

| 28 | 10 | Andrew Sutton | h3. Monitoring and Plotting |
| 29 | 10 | Andrew Sutton | |
| 30 | 11 | Andrew Sutton | There is an on/near-line monitoring script along with an offline version of which are also housed on the FTBF machines. |
| 31 | 11 | Andrew Sutton | You need to have kinit rights to user extbeams (I need to make this more easily accessible -ATCS). |
| 32 | 11 | Andrew Sutton | |
| 33 | 11 | Andrew Sutton | To run the offline script: |
| 34 | 11 | Andrew Sutton | <pre> |
| 35 | 11 | Andrew Sutton | ssh -XY extbeams@ftbf-cr-02.fnal.gov |
| 36 | 11 | Andrew Sutton | cd mtestwire/ |
| 37 | 11 | Andrew Sutton | source py3/bin/activate |
| 38 | 11 | Andrew Sutton | python plot_wires_offline.py /home/tmp_forJason/EDIT2018/MWPC-MCenter/data/filename.dat |
| 39 | 11 | Andrew Sutton | </pre> |
| 40 | 11 | Andrew Sutton | |
| 41 | 11 | Andrew Sutton | To run the monitoring script: |
| 42 | 11 | Andrew Sutton | <pre> |
| 43 | 11 | Andrew Sutton | ssh -XY extbeams@ftbf-cr-02.fnal.gov |
| 44 | 11 | Andrew Sutton | cd mtestwire/ |
| 45 | 11 | Andrew Sutton | source py3/bin/activate |
| 46 | 11 | Andrew Sutton | python plot_wires_nearline.py /home/tmp_forJason/EDIT2018/MWPC-MCenter/data/filename (*note there is no .dat ending) |
| 47 | 11 | Andrew Sutton | </pre> |
| 48 | 11 | Andrew Sutton | |
| 49 | 11 | Andrew Sutton | Both scripts output images to: /home/nfs/extbeams/mtestwire/images |
