Hi Paul,
The two issues are unrelated - the FSLeyes problem is a bug which was
fixed a few months ago - if you upgrade to the latest version it will
go away.
As for the dual regression issue, is there any useful information
(e.g. error messages) in the scripts+logs directory?
Cheers,
Paul

When I attempt to run a group ICA from the command line on these data (the individual subjects' filtered/cleaned functional data warped to standard space), MELODIC runs just fine, and I get a group list of ICs (melodic_IC) and other output files. However, when I then attempt to run a dual regression on these ICs using the subjects' standard-space functional data, the output I receive is just the scripts+logs folder, and nothing else.
