readraw just stops working

[ispybadguys]

I installed this on one MBP running Catalina (10.15.7) and it worked fine and then just quit. I tried it on another machine and the same result. It works for a while and then quits. When it quits it returns a empty cell array and no error messages. It is great while it works

A call with ImageFullFileName='/Users/kurt/Documents/MATLAB/MatlabAstrophotography/March 5 2021/DSC01725.ARW'

returns

[ImageRaw,info,output] = imread(ImageFullFileName)

ImageRaw =

0×0 empty cell array

info =

struct with fields:

software: '/Users/kurt/Documents/MATLAB/MatlabAstrophotography/ReadRaw/private/dcraw_maci64'

output =

 []

Hello @ispybadguys

I would suggest you try to move your ARW file to a location that has no spaces in the path, e.g. in /tmp. Then report back on the importation process. Be aware that DCRAW is not supported any more. This means new file formats will not be readable with it. That's why other readers are suggested, and supported by matlab-readraw, as external commands.

Thanks. You have been most helpful. That worked. What other reader would you suggest?

Hi Kurt,
I would suggest you have a look at, for Mac OSX:

• https://support.apple.com/en-us/HT208967
• https://www.exiv2.org/download.html
• https://www.libraw.org/download (the binary tools are required, and should be in the PATH)
