Without seeing the error message, the readers cannot know, what's going wrong. The screenshots are not really helpful to clarify details.

In Windows, the dir command will usually return the first two values as dots, not a file name. When I run this code:

fnames = dir;
for i=1:length(fnames)
    folder=fnames(i).name
end

the first two values for ‘folder’ are:

folder =
    '.'

folder =
    '..'

See if setting your for loop to begin at 3 instead will help:

for i = 3:length(fnames)

You have not stated the error, so this is a guess as to what the problem actually is.

Thank you for your response. the error msg is attached.

I suspect it is throwing the error on the asterisk, since it interprets that a a wildcard, and is interpreting ‘i’ as a character, further complicating your code:

fna=dir([folder,'\3D\','i*','.dcm']);
                         ↑

It is likely better to use sprintf than (incorrectly) concatenating the strings.

Try this:

fna = dir(sprintf('%s\\3D\\%d.dcm', folder, i));

Remember that the first two values for ‘folder’ are not valid file names, so consider something like this:

for i = 3:length(fnames)
    folder = fnames(i).name;
    fna = dir(sprintf('%s\\3D\\%d.dcm', folder, i-2));
    ...
end

Experiment to get the result you want.
