I'm trying to run a second level analysis with feat, and flame keeps bombing
with the error:
An exception has been thrown
Runtime error:- detected by Newmat: matrix is singular
My 2nd level design is very simple - 3 evs with no colinearity, running
aboout 60 subjects, but we have plenty of memory & swap.
What I noticed was that the link to the tdof_t* files was broken - I tracked
this down to the total absence of any tdof_t* files in the 1st level
analysis directories. Is this normal, and if not, what could I do about it,
short of rerunning my 1st level analyses again? Is there some way I could
create such files if they're necessary?
Thanks,
