problems to open images after I have saved it in a folder

Hello, I have a problem with my work. My program can read some images from a specific folder, process and study them (differents features of them). When I have processed these images, I would save them in a different folder than the original. I did it, but when I want to open these (with Paint or another), it's impossible. I have been searching, but I can't find a good solution and neither my fault. This is my code:

function mostrar2

%load my processed images (for the moment are matrix)
load archivoimagenesfinales

[stat,struc] = fileattrib;
PathCurrent = struc.Name;

FolderName = ['imagenes'];
PathFolder = [PathCurrent '/RESULTADOS DE ESTUDIOS DE IMAGENES/' FolderName];
mkdir([PathCurrent '/RESULTADOS DE ESTUDIOS DE IMAGENES/'], FolderName);

for k=1:length(grupoimage)
    matriz=grupoimage(k).im;

      imagennumero=sprintf('imagentratada%d.bmp',k);
      %save as image in the usual folder
      imwrite(matriz,imagennumero);
      save([PathFolder imagennumero])

end
end

Thanks in advance

Why is the save() function call in there??? Can you attach one of the files that it made?

Because with imwrite() I can save the matrix in '.bmp'form (that what I want) but in the folder where I'm working.

I thought with save() I could save this file in '.bmp' in the folder created for me, but I think is saved in MAT-file, that why I can't open the files saved in my folder? If I open these from MATLAB, I get a file in MATLAB Editor... I definitely don't know how can I save images in another folder than which I'm working...

Try this:

% Get the name of the file that the user wants to save.
% Note, if you're saving an image you can use imsave() instead of uiputfile().
startingFolder = userpath
defaultFileName = fullfile(startingFolder, '*.*');
[baseFileName, folder] = uiputfile(defaultFileName, 'Specify a file');
if baseFileName == 0
  % User clicked the Cancel button.
  return;
end
fullFileName = fullfile(folder, baseFileName)
imwrite(matriz, fullFileName);

Thanks for the help! Finally, I made a...mix?, because I don't want "to have to choose the folder" but saved a number of images on this directly, or by default, I don't know how to say that exactly, but I don't want a window open for every image and have to select folder, name, ec... That what I do and it works!

function pcdi

load archivomatricesfinales
grupoimage; %im

n=length(grupoimage);

[stat,struc] = fileattrib;
PathCurrent = struc.Name;

%crear las rutas (Path) para carpetas y archivos
FolderName = ['imagenes'];
PathFolder = [PathCurrent '/RESULTADOS DE ESTUDIOS DE IMAGENES/' FolderName];
mkdir([PathCurrent '/RESULTADOS DE ESTUDIOS DE IMAGENES/'], FolderName);

for k=1:n

      matriz=grupoimage(k).im;
      imagennumero=sprintf('imagentratada%d.bmp',k);
      fullFileName=fullfile(PathFolder,imagennumero);
      imwrite(matriz,fullFileName);

end

Again, thanks a lot!
