Hello Experts,

I'm new to conn and have had no real problems until now, but here goes. After creating some ROIs/seeds in wfu_pickatlas and importing them into conn I get the following error message when running my first-level analyses:

Error using fseek
Invalid file identifier. Use fopen to generate a valid file identifier.

Error in conn_get_slice (line 15)
fseek(handle,4*sum(V.size.Nv(1:slice-1))*V.size.Nt,-1);

Error in conn_process (line 1662)
[y,idx]=conn_get_slice(Y,slice);

Error in conn_process (line 25)
case 'analyses_gui_seed',disp(['CONN: RUNNING ANALYSIS STEP (ROI-to-ROI or seed-to-voxel analyses)']); conn_process([10:12,15],CONN_x.Analysis);

Error in conn (line 3085)
conn_process('analyses_gui_seed',CONN_x.Analysis);

Error in conn_menumanager (line 102)

feval(CONN_MM.MENU{n0}.callback{n1}{1},CONN_MM.MENU{n0}.callback{n1}{2:end});

CONN v.14.n
SPM8 + ArtRepair Beamforming DEM FieldMap MEEGtools wfupickatlas
Matlab v.2013a

I recently installed the pick atlas and had no trouble prior to that. Could that somehow be the problem?
Additionally, conn seemed to get through most of my subjects (103 out of 108; first-level analyses) before encountering the error, if that helps.
Any help would be greatly appreciated!

Thank you all (in advance)!
Matt
