How to access elements of nested structures

Hi all,

I have a nested structure. A 1*1 struct(data) contains a 1*1 struct(metadata) and a 245*1 struct(results). I want to access the column 'id' within a 245 *1 struct. Can anyone teach me how to do that? the nested structure is attached here.

Try this:

s = load('data.mat')

s = struct with fields:
    data: [1×1 struct]

id = {s.data.results.id}'

id = 245×1 cell array
    {'GHCND:USC00310090'}
    {'GHCND:USC00310184'}
    {'GHCND:USC00310212'}
    {'GHCND:USC00310241'}
    {'GHCND:USC00310286'}
    {'GHCND:USC00310356'}
    {'GHCND:USC00310375'}
    {'GHCND:USC00310506'}
    {'GHCND:USC00310576'}
    {'GHCND:USC00310645'}
    {'GHCND:USC00310674'}
    {'GHCND:USC00310724'}
    {'GHCND:USC00310750'}
    {'GHCND:USC00310843'}
    {'GHCND:USC00310901'}
    {'GHCND:USC00310982'}
