Dear All,
I'm running a 2-step regression by taking the residulas of a a
first-level and using them into another first level.
However, as I run the "second" first-level I consistently get the
following error:
Prestats
Total original volumes = 150

etc ..
As I inspected the input data file ("sub203_Flobs_Res.nii.gz" above --
which is simply a copy of the res4d.nii.gz file in the stats folder of
the "first" first-level analysis) I noticed that by when the process has
finished (and given the error above) it is empty, yet I am sure that it
was not empty before launching the feat script.
Ideas what I'm doing wrong?
all the best
