Expected one output from a curly brace or dot indexing expression, but there were 3 results.

I want to access the vectors inside a structure and assign them independently to a variable (so each variable is a vector). However, when I try indexing the structure to obtain the first vector I get an error.
Here is what I am doing.
Test 1:
ns = data.NodeSets.Data(1) % Line 17
and I get "Expected one output from a curly brace or dot indexing expression, but there were 3 results."
Test 2:
ns = data.NodeSets.Data{1} % Line 17
and I get "Expected one output from a curly brace or dot indexing expression, but there were 3 results."
Test 3:
data.NodeSets.Data % Line 17
and I get a set of three vectors of type double but I can't assign them to any variable as I am only able to see them in the command window

Sorry, but that is all a bit complicated, please just save your variable, which you call "data" in the above question, in a .mat file and attach that.
save data data

You just need to explore your structure to understand what is happening. You have 3 NodeSets in your structure. The indexing you are using is trying to return the first value for each NodeSet

You need to also index the NodeSet. The code below returns the first value of the first NodeSet.
load data
ns = data.NodeSets(1).Data(1)

That is a completely different scenario than the one answered here. Please create a new question.
