How do I specify a filename path when using PARFOR?

I am trying to perform a bootstrapping technique of sorts for image processing and reconstructions. In order to do so, I am using a random number generator to select, open, and produce different combinations of dicom files. Each combination, referred to as a "bootstrapped image", takes ~5 minutes to produce when done locally. Since I want to generate 1000+ bootstrapped images, I would like to run my code in parallels.

If a use PARFOR as indicated below, the process crashes when calling dicominfo(filename). It gives the message: Error using dicominfo>getFileDetails (line 389) File "Test3.dcm" not found.

If I run the code as only a FOR loop it locates the file to open without a problem.

I have tried including the path in the filename and having it in the same directory as the function I am running.

I am trying to add the containing folder (C:\Documents and Settings\My Documents\BootstrappingTrial) into the AdditionalPath section under "Manage Cluster Profiles" but again this doesn't seem to help. (However I'm not entirely sure what path I should be putting under here.)

Is there anything I can do to remedy this?

Thank you.

clear;

N = 100; % number of files to sample from

parfor j = 1:1000

      Y = zeros(32,32,1,10);

      n = round( (N-1)*rand(10,1) + 1 ); % produces 10 random numbers b/w 1 and N

      for i = 1:10

          filename = strcat('Test',num2str(n(i)),'.dcm');

          info=dicominfo(filename); %%%%%%THIS LINE IS WHERE THE PROBLEM OCCURS
          [Xa,~] = dicomread(filename);
          X = Xa * info.private;

          Y(:,:,1,i) = Y(:,:,1,i) + X(:,:,1,i); %%True function is more complicated but you get the point... 

      end

      filename2 = strcat('Bootstrapped',num2str(j),'.dcm');
      dicomwrite(Y, filename2); % Write bootstrapped image to a new file

end

Are you using multiple cores on the same system, or are you using a distributed computing system?

Thank you for your response Walter. I am using a distributed computer system.

UPDATE: I have found that if a move the files into a shared folder on the server then it seems to find the files. I would still prefer though to keep the files on my own computer and link them if necessary.
