Hello FSL Experts,

We have discover that for a few sessions our block design paradigm started
earlier than our scan acquisition. Aside from subtracting the delay from
the original onset times in our 3 column format EVs, I believe we should
also model out and ignore the last TRs which represent an unanticipated
(and unwanted) extended final rest block.

Is creating a 3 column format that represents the end TRs enough to ensure
they are not interpreted as "rest" or is there a more sound way to
de-weight/unassigned those TRs?

A second idea I had that may work (or may just expose my ignorance to how
confounding EVs are applied), involves altering the confounding matrix
that is outputted from fsl_motion_outliers to exclude the end TRs.


Any insight/wisdom is gratefully appreciated!

Thank you,
Jacob
