Concerning the following code:
D = 'C:\Users\[...]folder\';
S = dir(fullfile(D,'*.tif'));
for k = 1:numel(S)
OGFile = imread(fullfile(D,S(k).name));
imshow(OGFile);
[centers,radii] = imfindcircles(OGFile,[5 15], 'Sensitivity',0.85, 'Method', 'TwoStage', 'EdgeThreshold',0.20);
h = viscircles(centers, radii,'Color','c', 'LineWidth',1.5, 'EnhanceVisibility',false);
F = getframe;
%save as originalfilename_circles.tif
end
I currently load all files in "folder" and perform the imfindcircles and viscircles functions upon them. I use getframe to capture the viscircles image, and would like to know how I can save this as [original file name]_circles? As in, append the string "_circles" to the end, and save to folder D.
I know the latter part includes:
imwrite(F.cdata,[filename]);
but am not sure how to specify directory and new file name there.
Thank you so much for any help :) Please let me know if there's any better way I could execute the above code, and forgive any mistakes here! I am very new to matlab.

You should be able to separate the path, name and ext of the full filename using fileparts. That should make it reasonably straightforward to append your "_circles" to the filename. Perhaps a modification something like:
D = 'C:\Users\[...]folder\';
S = dir(fullfile(D,'*.tif'));
for k = 1:numel(S)
fFname = fullfile(D,S(k).name)
OGFile = imread(fFname);
imshow(OGFile);
[centers,radii] = imfindcircles(OGFile,[5 15], 'Sensitivity',0.85, 'Method', 'TwoStage', 'EdgeThreshold',0.20);
h = viscircles(centers, radii,'Color','c', 'LineWidth',1.5, 'EnhanceVisibility',false);
F = getframe;
[fF_path,fFname,fFext] = fileparts(fFname);
fFnameExt = fullfile(fF_path,[fFname,'_circles',fFext]);
% Maybe you should consider to save to a results-directory and not
% fill one directory with both original data and analysis results
%save as originalfilename_circles.tif
end

Good that it helped.
Something like that ought to be OK, but I think it should look like:
[fF_path,fFname,fFext] = fileparts(fFname);
SavePath = 'C:\[path]\';
fFnameExt = fullfile(SavePath,[fFname,'_circles',fFext]);
You might try to build the SavePath-variable with fullfile too - to extract the relevant parts from fF_path if you need that and possibly to make transport of your scripts to UNIX-like OSes easier - but then I don't know how to handle the MS "C:"-drive-designation, so that might be tricky (or trivial?).
