Example of failing command

pyhrf_jde_vem_analysis -o Processed_EVENT_cos_hp1e5-d 1.25 --drifts-type cos --hrf-hyperprior 100000 2.5 ../Masks/stanford_willard_parcellation.nii Paradigm/paradigm_events_session-2.csv Preprocessed/EVENT.nii

Note: option argument "-d" not separated from output directory. Command line is parsed without error and pyhrf crashes.

Output produced:

Expected behavior:
Command line parsing error or output by phyrf pointing the problem encountered with the command line.
