============================ Acces of NA49 DSTs on CASTOR (Tatjana Susa) ============================ The proper (castor) filenames one can find in my public directory: /afs/cern.ch/user/t/tsusa/public/DSTS The main steps are: 1.) From our Web page one should pick production tag. For example, for 99 p+p data it is 00D. 2.) In /afs/cern.ch/user/t/tsusa/public/DSTS for each production, there is a subdirectory named by production tag. In case of 99 p+p data, one should go to /afs/cern.ch/user/t/tsusa/public/DSTS/00D 3.) In these subdirectories, for each run there are two types od files. One of them has extenstion .castor the other .map .map files contain the FATMEN and the corresonding castor filenames. This is convenient if one would like to look at the particular chunk in one run. For example, to get castor filename for third chunk of run 2907 (99 p+p data), //CERN/NA49/DST/R99B/2907/MAY00/PRO/R2907_03-03.DS one should look in /afs/cern.ch/user/t/tsusa/public/DSTS/00D/2907.map ------------------------------------------------- //CERN/NA49/DST/R99B/2907/MAY00/PRO/R2907_01-01.DS /castor/cern.ch/na49/tape/Y27659/Y27659.129.al //CERN/NA49/DST/R99B/2907/MAY00/PRO/R2907_02-02.DS /castor/cern.ch/na49/tape/Y27659/Y27659.130.al //CERN/NA49/DST/R99B/2907/MAY00/PRO/R2907_03-03.DS /castor/cern.ch/na49/tape/Y27659/Y27659.131.al //CERN/NA49/DST/R99B/2907/MAY00/PRO/R2907_04-04.DS /castor/cern.ch/na49/tape/Y27659/Y27659.132.al ..... --------------------------------------------------- So, instead of //CERN/NA49/DST/R99B/2907/MAY00/PRO/R2907_03-03.DS one should now use the filename /castor/cern.ch/na49/tape/Y27659/Y27659.131.al In [run_number].castor files I've extracted only the castor filenames for particular run. This is convenient if one wants to process the whole run. For example, 2907.castor looks like: /castor/cern.ch/na49/tape/Y27659/Y27659.129.al /castor/cern.ch/na49/tape/Y27659/Y27659.130.al /castor/cern.ch/na49/tape/Y27659/Y27659.131.al /castor/cern.ch/na49/tape/Y27659/Y27659.132.al /castor/cern.ch/na49/tape/Y27659/Y27659.133.al /castor/cern.ch/na49/tape/Y27659/Y27659.134.al /castor/cern.ch/na49/tape/Y27659/Y27659.135.al /castor/cern.ch/na49/tape/Y27659/Y27659.136.al .... To process the whole 2907 run, one should copy 2907.castor file, add at the top DSPACK Input Files and use this file as an input for the program.
