Access data across multiple ODSs

ODS with consistency_check=False can be used to traverse data across multiple ODSs

from omas import *

# define a ods to collect multiple ODSs
master_ods = ODS(consistency_check=False)

# populate master_ods with a 5x3 grid of ODSs each having their data
for k in range(5):
    for j in range(3):
        ods = ODS(consistency_check=False)
        ods['data'] = k
        master_ods[k][j] = ods

# print data aggregating across ODSs
print(master_ods[':.:.data'])

This will return:

[[0 0 0]
 [1 1 1]
 [2 2 2]
 [3 3 3]
 [4 4 4]]
