Dear All,

I am trying to read the attached json file (with just three samples) with the attached viewjason.py script when I load it I seem to only "see" 1 sample and a

X=ds.getData('currFoc') [see my viewjason.py]

only give me a scalar instead of a 3D vector. Thank you for any help. All the best, -- Philippe.

PS: the ds= load_dataset (...) gives after a print(ds) [I have 9 variables with 40 output recorded] and just made three samples for testing purpose.

Sampler dataset.

Number of samplers: 1

Number of samples: 3 per generation

Available design variables (9) :

currFoc
currMat
gunE
gunPhi
lin1E
lin1Phi
lin1dx
lin1dy
lsrSzR
