hello –

Our forum software changes how hyphens appear, so it can be difficult to tell exactly what you wrote. I think you have two hyphens before g and b, but these should only have one. Try running this:

"C:\Program Files\BrainSuite21a\bdp\bdp.exe" 2523412.bfc.nii.gz --tensor –-nii 2523412.dwi.nii.gz -g 2523412.dwi.bvec -b 2523412.dwi.bval

and see if that fixes the problem.

thanks,
David

I have done what you said, but it still didn’t work. I don’t know how to fix it.

Two hyphens before tensor and nii, and one hyphens before g and b.

[David Shattuck]

If you enclose your text with pre tags, it should show it as you wrote it. [code] doesn’t work, unfortunately. pre uses angle brackets rather than square brackets.

I am not near a Windows machine at the moment, but I just tried this on Linux using the data from https://brainsuite.org/tutorials/dtiexercise/ and it started. I copied the arguments from your post.

I will try it on Windows later today and get back to you.
