contrast estimation SPM12

Hi,

I've got this warning:
PPI Contrasts were not estimated for some reason.
When running the following PPP(P):

cd(fullfile(parent_folder, subject_list{1,i}, 'OST\1st_lvl_26c'));
P.subject=subject_list{1,i};
P.directory=pwd;
P.VOI=[pwd filesep 'dACC_6_22_30_r5_mask.nii'];
P.Regions='dACC_6_22_30_r5_mask.nii';
P.Estimate=1;
P.contrast=0;
P.extract='eig';
P.Tasks={'1' 'ISE' 'INCL' 'ESE' 'ReINCL'};
P.Weights=[];
P.analysis='psy';
P.method='cond';
P.CompContrasts=1;
P.Weighted=0;
P.Contrasts(1).left={'ESE'};
P.Contrasts(1).right={'ISE'};
P.Contrasts(1).STAT='T';
P.Contrasts(1).Weighted=0;
P.Contrasts(1).MinEvents=1;%Block design with 1 long event per condition
P.Contrasts(1).name='ESE > ISE';
save P;
PPPI(P);

I'm on SPM12(6685).
Any idea?

Regards,

Alexandre

What was the complete screen output about the error?

RE: contrast estimation SPM12

Did all tasks occur in all runs? In not, change the '1' in P.Tasks to '0'.

Best,
