Hello,

We are piloting a few different fMRI sequences for a new resting state experiment and are now wondering how we can assure that we pick the best quality data. One of the sequences is a multiband ultrafast fMRI sequence and we're wondering whether we are picking up some spuriously high correlations due to the simultaneous image acquisition. Is there a good way of detecting these correlations? We tried some standard seed-based (PCC-whole brain) functional connectivity and it looks fine but maybe there is a better way of ensuring accurate correlation values?

Any help would be greatly appreciated!
