Having trouble rewriting a DICOM file with metadata: converting table to structure

Currently, I have my metadata (from a different source) as follows:

Is there any way to convert a 216x2 table into a structure that is 1x1 but with 216 fields of 216 values? something more like this:

I have also attached the original metadata table (with some fields removed) as a reference.

Hi Johnathan,

Your issue may be solved this way:

% If 'T' is the variable holding the table, 
C = table2cell(T);
C = C';
C = C(:);
S = struct(C{:})

It's farily interesting what's going in here, unde the hood.

We're trying to create a struct using the syntax: struct(field1, value1, field2, value2, ..., fieldN, valueN). So we need to be passing all 216*2=432 fields in this way.

To start with, we convert the table 'T' into a cell array which is easier to manipulate.

Then we linearize this 216x2 cell array into a one dimensional cell array. (We need to transpose the Cell Array first, to linearize in the right order)

Finally, we make use the fact that a cell array when indexed using {} in a range, would produce a comma-separated list which can be passed into functions where each element acts like a different function argument.

Hope it helps!
