Need help on matlab table
显示 更早的评论
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?

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()
