anatomy of a data file name
- Taken from theta13-offline email thread
- Harry Themann's question
Here is an example
daq.NoTag.0014139.Physics.EH1-Merged.SFO-1._0318.data
first.second.third.fourth.fifth.sixth.seventh.eighth
the wiki page https://wiki.bnl.gov/dayabay/index.php?title=Accessing_Data_in_a_Warehouse implies that there are
- runs -- third group in filename
- ids -- filename without extension
- fileSets-- defined in warehouse, the example produces no hits
- appl -- sixth group in filename
what about the other groups in the filename? would i ever want to search on those groups?
- Simon Patton's answer:
The DAQ file naming convention is documented in section 4 of DocDB document#3442.
In the offline this has been extended to include 'd2r.' and 'recon.' as file prefixes, and we have our own list of applications.
- Chao Zhang' answer:
For raw data:
daq.<tag name>.<run no.>.<stream type>.<stream name>.<application name>._<file no.>.data
Defined in DocDB document#3442
