I may have a more knotty interpolation problem. In a recent fMRI session, we accidentally collected one of 4 runs with the wrong protocol, using a TR of 2070 ms instead of 2000 ms. This is a periodic visual stimulation paradigm, so I think the precision of the timing does matter a bit more than with a block design. I was hoping to salvage this run by interpolating my dataset from 138 volumes @ 2070 ms to ~142-143 volumes @ 2000 ms. Is this feasible, and if so, how would I go about it? I do recall reading in AFNI documentation that frequencies > 1/2 of TR could not be well interpolated, and perhaps that will be a problem here.
Thanks,
Jeff
