Hello Matthew and Steve,

I'm using
5.0.5-1~nd70+1 of NeuroDebian of FSL.
(Just installing the newer one right now, mean 5.0.6... :)
Melodic still works with a data set I analysed some weeks ago.  
(Attached the fslhd output as 4d.txt.)

Following datasets don't work:
I attached the outputs of FSLHD, and I already compared the 2 series  
I'm concatenating (1st.txt and 2nd.txt). Only differences in
pixdim7
qto_xyz:1 til 3
sto_xyz:1 til 3

The single run with another multiband dataset also didnt work. There's  
single.txt attached.

Thanks!
Matthias
