how to use power spectrum

Submitted by cxl298 on Fri, 08/10/2012 - 07:31

Hi,
I'm trying to use the REST Power Spectrum tool, but unfortunately with no success.
When i click on it, it asks for an EPI brain map to be loaded.
When i do feed in a EPI, slice viewer pops up with the small EPI brain maps loaded as the 'underlay' in the bottom right corner, and nothing happens.

What do i do next?

Could you see any error message in commond line of MATLAB?
Power spectrum will read all dataset in a folder,  and calculate the power spectrum of time series voxel-by-voxel

 Hi Sandy,
there weren't any error message on the MATLAB command window, but it was a MATLAB issue indeed.
Luckily it's working now.

Thanks,
Christian
