To run o2-eve you need to have a computer with linux or mac with properly build O2. There are no special hardware requirements, but for performance it is better to have discrete graphic card.
for o2-eve to run you should:
- have in the working folder:
.o2eve_configfile (available from EventVisualisation/Scripts)o2sim_geometry.root(copied from simulation folder)o2sim_grp.root(copied from simulation folder)
- have (somewhere, specified by command line parameter) folder with json files (f.e
/home/ed/jsons) - have (somewhere, specified in
.o2eve_configfile) folder with simplify geometry files (f.e/home/ed/geom/O2)
Here are sample commands:
alienv enter O2/latest-dev-o2
cd /home/ed # working folder containing .o2eve_config, o2sim_geometry.root and o2sim_grp.root
o2-eve -o -d /home/ed/jsons| parameter | description | status |
|---|---|---|
| i | displaying ITS tracks from o2trac_its.root and clusters from o2clus_its.root |
(under development) |
| j | reading from *.json files (non online mode). require specification of json folder with -d |
|
| o | online mode. require specification of json folder with -d |
|
| r | randomly generated tracks | (test option, switched off) |
| t | displaying TPC tracks from o2trac_its.root and clusters from o2clus_its.root |
(under development) |
| v | displaying data from sample ROOT file (vsd) | (development test usage only) |
| f file | location of AOD file containing data to be displayed | (under development) |
| d folder | location of json folder - a folder where json files from workflow data are located |
