How to select / extract an array from a structure corresponding to other data type inside the same structure file?

Hi,

Say that I have a structure that contains different types of data type (attached).

I want to get the maximum value in one of the field (double type, 'MeanIntensity') using max, then I want to select the field (Matrix array, 'DataBinary') corresponding to its maximum value, then save it on a separate matrix array. Any idea on how to do this?

Thanks for any suggestions and help.
