Load only specific substructures from a mega-structure.

Hello,

So I have many .mat files each one consisting of one structure (data) that contains another structure (files) which contains multiple other structures (segment01,segment02 and so on).

Let's say I want to access only a specific segment, eg. segment01. I have to load the .mat file and then do something like segment01=data.files.segment01.

This takes a lot of time. I know that if I had my .mat in the form data.Segment01, data.Segment02 etc I would easily load only a speciifc substructure but I do not know how to access only data.files.Segment01. Is there any way?

Thanks

The question is not clear. Please explain more

Maybe you are looking for dir, fieldnames and getfield

I have some .mat files. subject01.mat,subject02.mat etc. Each file contains multiple segments that are in nested structure so to access segment01 of subject01 I should do the following:

load('Subject01.mat') 
segment01 = data.files.Segment01. 

The 1st step takes a lot of time because it has to load all the substructures (data.files.Segment01,data.files.Segment02 etc.) I want to speed up step 1 by loading only data.files.Segment01

You can't load only part of data

I see... Thanks for letting me know
