Dear Conn users

I am having some trouble with running the first level  analysis in the newest version of Conn (13f).
I loaded the realigned, slicetimed and normalized functional images (analyze format) and the corresponding coregistered and normalized segmented images (wc1*, wc2*, wc*3). This went perfectly fine for some but not all subjects. In appr. half of the subjects there seems to be no BOLD variance explained for the confounds  (which is improbable). Still the vx2vx connectivity distribution looks fine (the original distribution shifted to the right, centered without the confounds).

(Also in the first level analysis results, there are no connectivity maps displayed for  the same subjects)
(motion derivative order 1, dimension 6; white matter /CSF derivative order 0 dimension 3).

Any help would be very much appreciated!

Best
