Need help on matlab table

I have a text file with object name like 'ABC_01.REST.BKP.Blr.RR.nii' and classifier. I want to loop through each object name based on the classifier but dot in file name is creating a problem, Any idea how to handle this?

  ABV_0016.REST.blr6.dtAROMA_MNI.nii  Controlled 
  ABV_0017.REST.blr6.dtAROMA_MNI.nii  Syndrome 1 
  ABV_0019.REST.blr6.dtAROMA_MNI.nii  Syndrome 2 
  ABV_0022.REST.blr6.dtAROMA_MNI.nii  Syndrome 2 
  ABV_0030.REST.blr6.dtAROMA_MNI.nii  Controlled

What is your input data and what is your intended output?

[Tanu Shree]

My input will be classifier name like in above mentioned case Let's say If I pass Controlled it should give me two file name ABV_0016.REST.blr6.dtAROMA_MNI.nii and ABV_0030.REST.blr6.dtAROMA_MNI.nii.

You misunderstood me. The text you posted is not valid Matlab syntax, so what is your exact data?

Assumption: You have a text file that contains exactly the five lines of text formatted as code in your question.

Run the function cssm as in this example

>> object_names = cssm( 'd:\m\cssm\cssm.txt', 'Controlled' )
object_names =
  2×1 cell array
    {'ABV_0016.REST.blr6.dtAROMA_MNI.nii'}
    {'ABV_0030.REST.blr6.dtAROMA_MNI.nii'}
>>    
>> object_names = cssm( 'd:\m\cssm\cssm.txt', 'Syndrome 2' )
object_names =
  2×1 cell array
    {'ABV_0019.REST.blr6.dtAROMA_MNI.nii'}
    {'ABV_0022.REST.blr6.dtAROMA_MNI.nii'}
>> 

where

function    object_names = cssm( ffs, classifier )
   
    fid = fopen( ffs, 'rt' );
    cac = textscan( fid, '%s%[^\n]', 'CollectOutput',true );
    [~] = fclose( fid );
    cac = strtrim( cac{1} );
    
    is_selected = strcmp( cac(:,2), classifier );
    object_names = cac( is_selected, 1 );
end

Comments:

• It's possible to use a loop, but I see no reason to do that.
• How does the dot in the file name create a problem?
• The space in some classifier values requires a special solution. In the function, cssm, I read the first "word" (i.e. the object name) and then the rest of the row to the second column.
• There are other solutions, e.g. using readtable()
