Hi - yes if you have done an F-test across the FLOBS basis functions you can resample the zstats or fstats into standard space and feed that into randomise.
You can use the ApplyXFM GUI to resample the stats into standard space - though if you used nonlinear registration you would need to do this on the command line.
However - the main question is that I'm confused that you're talking about both FLOBS and canonical HRFs - these are two distinct HRF options so I'm not sure quite what you've done...
Cheers.

According to the posts, back in 2008, there was no simple solution to this problem, as the first-level analysis doesn't produce copes for the canonical HRF, only the single basis functions.
