This line gives an error:

Unable to find image 'kaczmarj/neurodocker:v0.4.0' locally docker: Error response from daemon: manifest for kaczmarj/neurodocker:v0.4.0 not found: manifest unknown: manifest unknown.

I think it should be docker run --rm kaczmarj/neurodocker:0.4.0 generate [docker|singularity] --help removing the v before the version number.
