different number of slices in a within subject pre/post design
Hi all,
I'm trying to use conn to process some resting state data, and I've run into an issue that I was hoping you might be able to give me some advice on.
The study is a within subject placebo controlled drug challenge. Normally, there are 154 time points and 30 slices. For one participant on the drug visit, there are 154 time points, but only 26 slices (some error in the scanning! the placebo visit has the normal numebr of time points/slices) – resulting in an error during slice timing correction. Unfortunately, we've only got a very small sample, so can't afford to exclude this participant. Is there anything you'd suggest doing as an alternative?
Despite this not toolbox specific issue, conn's been brilliant!
Thanks,
A
