Yes, that's exactly what I am looking for. Raw waveform as a percent.

h-offset is the intensity offset (basically the mean signal). h.nii.gz is a complicated combination of the betas (regression coefficients) that is included for backwards compatibility. What do you mean by % signal change? Do you want the raw waveform as a percent?

Thank you, Doug.
Sorry for not being clear. Could you please tell me what h.nii.gz and h-offset.nii.gz are?
Also, do you have any recommendation on how to get % signal change on the signal intensity as oppose to % signal change on contrasts?
Thank you

It divides the contast (ces) by voxel-wise mean.
