Dear Alfonso

I received the same mista after I launched the conn, 
Could you figure out this problem?

The mistake which I received was 

ERROR DESCRIPTION:

Error using spm_slice_vol (line 32)
spm_slice_vol.c not compiled - see Makefile
Error in spm_read_vols (line 34)
Y(:,:,p,i) = spm_slice_vol(V(i),spm_matrix([0 0 p]),V(i).dim(1:2),0);
Error in conn (line 773)
CONN_gui.refs.canonical=struct('filename',filename,'V',V,'data',spm_read_vols(V));
Error in conn (line 135)
conn initfromgui;
CONN20.b
SPM12 + DAiSS DEM FieldMap MEEGtools
Matlab v.2021a

I would be appreciated if you can help me,

Best
