Read one specific file name

Hi,

I have "TRMM_2000_01_01_newntcl.csv" and "TRMM_2000_01_0108_newntcl.csv" files in the same folder. I need to read ONLY "TRMM_2000_01_01_newntcl.csv" file but the following code reads both.

Any idea?

cd ('C:\Users\<path>')
d=dir('TRMM_*_newntcl.csv');
ymdh=cell2mat(textscan([d.name], ...
            'TRMM_%4d_%2d_%2d_newntcl.csv', ...
            'collectoutput',true));

Use d(1).name to take the name of the first index, i.e., the first structure in the structure array.

It does not do any difference. Output is still the same.

Replace

    d=dir('TRMM_*_newntcl.csv');

by

    d=dir('TRMM_*01_newntcl.csv');

If I change to below, it only selects "TRMM_2000_01_01_newntcl.csv" file. But, I have 'TRMM_2000_01_01_newntcl.csv' upto 'TRMM_2000_12_31_newntcl.csv'

 d=dir('TRMM_*01_newntcl.csv');

Any idea?

Your question wasn't possible to answer. You provided too little information. Now you add a new requirement.

Idea

• formulate a rule that matches all files you want and which discriminates the rest. In your comment you tell which shall be matched, but not which should discriminated against.
• you will find that your rule cannot be met by dir in combination with a wildcard. Something else is needed. Try replace

    d=dir('TRMM_*_newntcl.csv');

by

    sad = dir('TRMM_*_newntcl.csv');
    cac = regexp( {sad.name}, '2000_[01]\d_[0-3]\d_' );
    ism = not( cellfun( @isempty, cac ) );
    d   = sad(ism);

This worked. Thanks.
