How to generate resting state fMRI data
Hi, All. Recently, i found some issues on how to generate resting state fMRI data. Can you tell me some more details about generate synthetic resting state fMRI data by using SPM? or papers about how to generate synthetic fMRI timeseries?

RE: How to generate resting state fMRI data
Hi Xiao,

I am generating by following steps(MATLAB)-
Generate random signal - randn.
Generate random integer(onsets) in the range of earlier signal - randi.
set the random signal high values at those integer indices.
Generate HRF with a given TR - spm_hrf.
Convolve it with the signal.
