Thanks very much for your reply (sorry for the new question, I was unable to comment on your reply!).
Following your instructions, with a fresh download of ImageJ and the toolbox, unfortunately the error message now reads ‘Timeout – DCRAW doesn’t seem to have processed this file’. Is there anything I can do to process the file first so that the DCRaw import function will behave please?
I would recommend doing a clean re-install of ImageJ (the JAVA bundled version) and the MICA toolbox as per the installation instructions. It usually is Mac users encountering issues and not the Windows users, so this should hopefully fix it. Yes, your file seems fine, as such my guess is a faulty folder path/installation or Java/ImageJ version conflict. Let me know if you were able to solve the issue and what solved it.
Apologies for the inability to post a reply/comment – I think I’ve fixed that and modified the forum.
The timeout means DCRAW isn’t producing any output. What file format are you trying to open? Maybe you could send me a version to test myself? Also, make sure the RAW file is located somewhere where there isn’t weird system protection (the software needs full read/write access to the directory containing the RAW file). So try somewhere like “documents”.
