General user:

Generally, you need "GRID certificate" and "CALICE VO" for downloading the MC mass production files from GRID SE. And you have to set up the proper grid environment, which depends on where you are working.

Now let's go to the common part for all user. Assume that you are working on bash shell.

1. setup grid environment. (Please ask your administrator)

2. voms-proxy-init -verify -debug -voms calice -valid 25:00 (from now, you could working on the grid for 25 hours with your certificate and CALICE VO )

3. export LFC_HOST=`lcg-infosites --vo calice lfc` (define the "LFC_HOST")

4. lcg-cp (Finally, you could use this command to download the mass production from grid se to your local computer)

One example for DESY user with bash shell.

For example, I perform the following steps to download the files from grid se to my local computer "/tmp/" directory.

$ . /afs/desy.de/project/glite/UI/etc/profile.d/grid-env.sh

$ voms-proxy-init -verify -debug -voms calice -valid 25:00

$ export LFC_HOST=`lcg-infosites --vo calice lfc`

$ lcg-cp -v --vo calice lfn:/grid/calice/shaojun/Electron_45GeV_10kevt_TBCern0806_01_dchxy_new_Mokka0607p01calice_001.slcio file: /tmp/Electron_45GeV_10kevt_TBCern0806_01_dchxy_new_Mokka0607p01calice_001.slcio (all in one line)

If you found any problems, please let me know.
