Ntuple-ology at hestia
startup of your account at hestia
- copy .login .cshrc and .alias files from ~e949/ to your own accont.
(You need to do "%setup e949" "%setup kofia" and "%setup cernlib"
to setup the E949 environment; the .login file does all of this .)
ntuples
- The "autorun" ntuples, which were created shortly after the
data was taken by the current best Pass2 job, from the monitors-to-disk
data, are stored
in /scr10/e949/autorun/pass2_xxx/ntuple/analyzed/ . Exactly speaking,
- /scr10/e949/autorun/pass2_1gamma/ntuple/analyzed/
- /scr10/e949/autorun/pass2_kbeam/ntuple/analyzed/
- /scr10/e949/autorun/pass2_km21/ntuple/analyzed/
- /scr10/e949/autorun/pass2_km22/ntuple/analyzed/
- /scr10/e949/autorun/pass2_kp21/ntuple/analyzed/
- /scr10/e949/autorun/pass2_kp22/ntuple/analyzed/
- /scr10/e949/autorun/pass2_piscat/ntuple/analyzed/
- /scr10/e949/autorun/pass2_pnn1or2/ntuple/analyzed/
- /scr10/e949/autorun/pass2_pnnl0/ntuple/analyzed/
- /scr10/e949/autorun/pass2_rsmon/ntuple/analyzed/
- All the scaler record ntuples (*.eos) are moved to
/scr10/e949/autorun/pass2_xxx/ntuple/eos/ .
source code
- The pass2 analysis code that created the autorun ntuples
are copied to /scr02/e949/pass2.020715/
(which is linked from ~e949/pass2/).
"%setup pass2 02" automaticall makes the access to the
code available.
- "%cd $PASS2_SOURCE" to go to the directory of the source code.
useful programs and scripts
- Since the size of the E949/E787 pass2 ntuples are huge,
the PAW-command uwfunc does not work with them.
The special program "uwfunc" was therefore prepared.
The execution file is available at /scr02/local/bin/uwfunc.
- For chaining many ntuple files, the kumac script "chain_nt.kumac"
by S.Chen and D.Jaffe are very useful.
%ln -s /scr10/e949/autorun/pass2_1gamma/ntuple/analyzed/ 1g
PAW> exec chain_nt ./1g 0 1gamma
PAW> nt/loop 1 analysis.f(0.)
A debugged kumac script is currently available at
~koma/work/e949/nt_ana/chain_nt_dj.kumac.

- The analysis-related information
will be distributed through
e949.pass1 (location for active discussion on analysis work)
and
e949.kofia (for updates on Kofia code).
