Thank you very much for the complete answer. Now I understand, and it works.
Best Regards.

>first run temporal-concat melodic. pick the IC you want and identify it in
the melodic_IC. split the melodic_IC into its components using fslsplit. lets
say you want to look only at the second component - use vol001 (!, not vol001
because the first will be vol000) from the melodic_IC split. feed this into the
DR script as the group_IC_map. for the subjects you need to specify the
preprocessed functional data of each subject, not any single-subject ICs.
