Command to run designer is:
singularity run --nv --bind .:/mnt designer2_main.sif designer -denoise -shrinkage frob -adaptive_patch -rician -degibbs -pf 1 -eddy -rpe_pair ${pa} -normalize -mask -b1correct -scratch /mnt/processing -nocleanup ${dwi} ${dwi_out}

It looks like ANTs is not installed in the singularity (or docker) image. I don't know if this is the correct place to submit this issue, if not, please let me know where best to submit an issue with the docker container.

Thanks in advance!
