1、 source initialize.sh 报错：在下载了新的ATLAS证书，申请了RUCIO VO权限之后，没有再像之前那样报出一大推错误，会显示TagAndProbeFrame: Package build succeeded，但会报出

CMake Error: Unknown argument --clean

CMake Error: Run 'cmake --help' for all supported options

另外关于rucio也会报出

 emi:

   No valid proxy present.  Type "voms-proxy-init -voms atlas"

 rucio:

   Warning: An ATLAS release was setup and rucio may not work.

            If you have rucio issues, retry with the wrapper version. 

            eg: lsetup "rucio -w"

 

2、目前可以运行python ZmassRun.py, 显示 worker finished: 并生成photonTestZmassDir文件，但仍存在failed to open file问题，且生成的文件为空。

failed to open file: file:///pnfs/desy.de/atlas/dq2/atlaslocalgroupdisk/rucio/mc16_13TeV/dc/38/DAOD_STDM2.12245160._000051.pool.root.1

新电流表在低电压时示数很稳定，高电压时（比如大于150V）示数波动较为明显，会有几pA的浮动，在临近雪崩时波动更为明显，会有百皮安的波动。

14:35 → 14:50 Silicon tracker & detector physics

Speaker: Junhua Zhang

1-生成了1E6个事例，正在用hadd命令合并

2-百分之八十六左右的Trk_pp_[0]是yifan自己用代码忽略了无法生成的events，是正确的数据，

下一步

1比较tag重建动量跟rec重建动量的“有效”events数，看有没有个数的出入。如果有，画events的图并归纳特征

2尝试生成event的坐标，试图找到偏转相关的参数。
