How can I extract data from a structure? I keep getting "The class struct has no Constant property or Static method named 'strains'." error

I am currently running the Ncorr software with matlab and need to pull the strain data from it.
The below is the data in structure form and I can't figure out how to get the values out of the "strains" section. I tried simply doing [struct.strains] but the I get the error "The class struct has no Constant property or Static method named 'strains'". I don't care how the values are presented, I just need the numbers to put in a research notebook.
>> handles_ncorr.data_dic
ans =
struct with fields:
displacements: [1×152 struct]
dispinfo: [1×1 struct]
strains: [1×152 struct]
straininfo: [1×1 struct]
Thanks for the help in advance and let me know if further information is needed!

ans.strains
The 'struct with fields' is the standard output line that tells you the class of the variable you just viewed, 'ans.'
