Hi Chris,

I am having trouble using dcm2niix from the command line and I was hoping you would be able to help. I am trying to convert diffusion weighted PAR/REC files to nifti. I supply the path directly to the .par file, however it returns the error "Error: output folder invalid: /path/to/par/file" when I do not have the  -o option set. Alternatively, I give the path to the folder containing the par files, but it gives an error saying there are no dicom files in the specified folder. My (paraphrased) command is here:

/path/to/executable -f outname /path/to/par/file

When I use the GUI, it works just fine, but given the volume of data I need to convert, using the command line utility would be much more convenient, and given the simplicity of the command I don't see any error in my syntax. Would you have any ideas as to what may be going on here? Any guidance is greatly appreciated.

Thank you,

Josh Robinson
