Hi Sathesan,

Thanks for helping me debug this, this seems to be related to an interaction with a rogue SPM toolbox, could you please copy/paste the following commands in your Matlab command-line window and let me know their output (that will be a long list of directories) and also send me the newly created debugging01.mat file?

path
which nifti
which spm_vol
filename=fullfile(fileparts(which('conn')),'rois','networks.nii');
a=nifti(filename);
b=spm_vol(filename);
save debugging01.mat a b;

Thanks
Alfonso
