Hi Chris,

Thank you so much for the clarification! I realized these were output saved directly within my original file after pre-processing. The outputs derived from dcm2niix actually starts with co, o and series of number (I was using an older version of MRIcron). I converted my images again using the current version and got one output file named the same way as my raw images. What were the difference between the three output files derived from the older version of MRIcron? Would it matters to use the output from older version vs. the current version?

Thanks a lot!
