re-use .mat file

$

Dear Conners,
I stopped functional and structural images preprocessing because I forgot to add one pre-processing step. I would like to use the same .mat file that in the previous analysis in order to avoid having to select each structural and functional image again and only include that new step. I have tried to rerun the analysis organizing the original structural and functional images in the same way that in the previous analysis (same path directory) and using the previous .mat file. As might be expected, the conn toolbox looked for preprocessing outputs that are not in that directory. When I cancel that search and I click on "structural" or "functional" options in the gui the error messages included below appear. How could I re-use the .mat file to avoid having to select the images again?
