Hello Anderson,
I am trying to perform multivariate analyses using PALM.
1) When i execute the following command using palm
palm -i modality1_4d.nii -i modality2_4d.nii -i modality3_4d.nii -m mean_mask.nii -d design.mat -t design.con -f design.fts -n 5000 -mv
i get the following warning message in MATLAB terminal, which keeps recurring. What does it mean? Can i ignore this warning?
=================================================================
Warning: Matrix is close to singular or badly scaled. Results may be inaccurate. RCOND = 2.313452e-20.

=================================================================
2) in the MANOVA/MANCOVA (with contrasts of response variables) what is the format for C.mset D.mset files? if my C.mset has 2 contrasts [1 -1 0 0]; [-1 1 0 0] , what should my D.mset file contain?
Thank you
Jay
