nu_correct error

[nooralsh]

I'm processing some fMRI data using the singularity distribution of NIAK_cog-1.1.3 and I am consistently running into an error at the nu_correct stage for the anatomical T1 volume. This may be similar to issue #366 but I will provide some more detail.

The first odd thing is that even though my script is set as follows:

opt.t1_preprocess.nu_correct.arg = '-distance 75';

you can see below that the -distance flag is set to 200. Following that is the error itself which I don't know how to address. I also could not find a way to turn off the nu_correct to bypass this issue (which I was able to do with the nu_correct for fMRI which was also failing). Any help would be appreciated, thanks!

Thanks a lot for the report.

The issue #366 is for nu-correct of nii fmri. It is a known bug that needs fixing.

The anat nu correct should work in nifti though and I am not familiar with the error message. It may have to do with that particular release/container. @poquirion any suggestion?
