Hi Owen,

Correction: add a comma (after the '1') in the following line so you can 
select just one image.

q   = spm_get([1, nscan(i)],'.img',str);

Another useful way to deal with many subjects and the 2nd level is to either 
put them all into one big fixed analysis first, so all the con images are in 
one folder.  Also, if you really want, you can try to have 10 contrasts per 
session so you can then easily filter those conimages which end on the same 
digit (i.e. for every session you select, e.g. con_*2.img). Put this of 
course, has to be considered beforehand. Also, if your sessions are in 
separate directories, using the filter option of the spm_get dialogue should 
help, assumed your contrasts match across subjects (which they should)...

Sorry for the tiny bug posted before,

Helmut
