Hi Ella,
In the logs subdirectory of one of the .feat folders that has failed, there should be 3 files beginning with feat3_film. Can you tar them up and send them to me?
Kind Regards
Matthew

We have both motion outliers and Pnm confounds for 18/20 participants, but the first level analyses have failed for 14/18 of them. It runs the Stats section, then an error occurs at Post Stats so none are computed. Here is the error message (taken from the Stats section into the Post-Stats section in case helpful):
