I am running the dwibiascorrect with ANTs, but I get the errors below:
bio-imaging@bioimaging:~/Documents/MRtrix$ dwibiascorrect -ants -mask mask.nii scan.mif scan_corrected.nii -force

I guess the problem is that the default setting of N4BiasFieldCorrection. Should I change something by myself?
Any suggestions? Thanks for your help!
