I have a dataset with 24 classes and 4320 samples and i m having program for it. If i use the same program for 68 classes with 4079 images it throws error. what i have to change?

It throws error in the following lines:

classIDs(i) = str2num(tline(index+5:end));
the code :
tline = fgetl(fid); % get the number of image samples
i = 0;
while 1
    tline = fgetl(fid);
    if ~ischar(tline)
        break;
    end
    index = findstr(tline,'.');
    i = i+1;
    filenames(i) = str2num(tline(1:index-1))+1;% the picture ID starts from 0, but the index of Matlab array starts from 1  
    classIDs(i) = str2num(tline(index+5:end));           
end

Tell me what i have to change. I used outex tc 00010 and now I have changed to tc14. Thanks in advance

What is the error message you are seeing? Also, can you provide a reproducible snippet of the code?

[Shan Sha]

I have attached my code with this. my error is:

Unable to perform assignment because the
indices on the left side are not compatible
with the size of the right side.

Error in tc14god>ReadOutexTxt (line 189)
    classIDs(i) =
    str2num(tline(index+35:end));

Error in tc14god (line 43)
[trainIDs, trainClassIDs] =
ReadOutexTxt(trainTxt);

What is the value of tline when that error is thrown?

[Shan Sha]

the value of tline when the error is thrown is= 000000.bmp 0 this is my first image in database

[Sachin Meena]

what is the value of tline(index+5:end)?

[Shan Sha]

the value of tline(index+5:end) is 1x108 char

[Shan Sha]

my actual code is this. please check with this. sorry for the inconvenience mam

Your 'testTxt' file seems to be empty, leading to the method 'ReadOutexTxt' to break before populating filenames and classIDs.

[Shan Sha]

my text file is not empty. i checked it

Can you attach the other dependencies here so that I can reproduce the issue and debug?

[Shan Sha]

other dependencies mean what does it mean?

[Shan Sha]

sorry for the delay sir.please solve the error. I have used outex 14 dataset which i couldn't upload with this

[Shan Sha]

this is the actual code. for this i have downloaded outex tc 14 dataset. sorry for inconvenience. please check with this code
