Change file names before saving

Hi,
I am cropping a several collaged images simulatonouesly. I am able to successfully crop the images but do not like how the file names are saved. Lets say I have two collages in my folder that I want to crop...I crop them but when I go to save them it saves them as IMG_001_001 to how many images are cropped from the first image and IMG_002_001 to how many images are cropped from the 2nd image. The amount of blobs are saved in array [152, 148]. So the total number of images being cropped is 300, how would I make it so when the images are saved it goes from IMG_001 to IMG_300?
%%
message = sprintf('Would you like to crop out and save each individual images?');
reply = questdlg(message, 'Extract Individual Images?', 'Yes', 'No', 'Yes');
% Note: reply will = '' for Upper right X, 'Yes' for Yes, and 'No' for No.
if strcmpi(reply, 'Yes')
for n = 1 : original_images
for k = 1 : numberOfBlobs(n)
thisBlobsBoundingBox = blobMeasurements{n}(k).BoundingBox;
subImage = imcrop(OG_images{n}, thisBlobsBoundingBox);
folder = 'C:/Users/Corey/Desktop/new zoop 2';
thisBaseFileName = sprintf('Image%03d_%03d.tif', n, k); % I know i would take out %03d_%03d and the n and k
% but how do I replace that or how do I the total numberOfBlobs
thisFullFileName = fullfile(folder, thisBaseFileName);
imwrite(subImage, thisFullFileName,'tif');
end
end
end

Try this:
%%
message = sprintf('Would you like to crop out and save each individual images?');
reply = questdlg(message, 'Extract Individual Images?', 'Yes', 'No', 'Yes');
% Note: reply will = '' for Upper right X, 'Yes' for Yes, and 'No' for No.
folder = 'C:/Users/Corey/Desktop/new zoop 2';
if strcmpi(reply, 'Yes')
for n = 1 : original_images
thisBlobsBoundingBox = blobMeasurements{n}(k).BoundingBox;
subImage = imcrop(OG_images{n}, thisBlobsBoundingBox);
thisBaseFileName = sprintf('Image%03d_%03d.tif', n, numberOfBlobs(n));
% but how do I replace that or how do I the total numberOfBlobs
thisFullFileName = fullfile(folder, thisBaseFileName);
imwrite(subImage, thisFullFileName,'tif');
end
end

@Louis-Philippe Guinard:
- Use fullfile to create the complete filename, rather than concatenating strings.
- Use fileparts to remove file extension from a filename, rather than buggy indexing.
- Read the num2str documentation, you current usage makes little sense. Or even better, use sprintf.
pnm = 'some path for a folder';
[~,fnm] = fileparts(matfilelist(itmat).name);
tmp = sprintf('%03d',filenumber);
save( fullfile(pnm,[fnm,'_Results',tmp,'.mat']), 'variable');
savefig(fig, fullfile(pnm,[fnm,'_Figures',tmp,'.fig']));
saveas( fig, fullfile(pnm,[fnm,'_Figures',tmp,'.png']));

Come to think of it, I really did write that line weird... Thanks for the heads-up! And thanks for the save as-is, I tried what you sent me and now it works!
