Below is the more detailed description of the problem that I've been
encountering:
emporal non-sphericity (over voxels) : ...REML estimation
ReML Block - 1
ReML Iteration : 1 ...NaN
Warning: Matrix is close to singular or badly scaled.
Results may be inaccurate. RCOND = -1.000000e+00.

Results may be inaccurate. RCOND = NaN.
etc.
Any insights on how to resolve this problem will be really helpful.
