Hi Doug,
sorry for having bothered you before checking closer. Just excluding the offensive run solved my problem... (now off to figuring out how to detect if I want to exclude to many timepoints in a run :))
best Sebastian

Hi Doug,
I have a number of runs with some bad k-space arcing artifacts that I still would like to analyse. Now spikedet-sess makes childs play to turn the detected spikes into a timepoint exclusion file. But when I try to use this file with fs-fast (from freesurfer v4.5 x86_64) I get errors from fast_selxavg3.m (see below). Do you have any idea how I can use tpefs for fs-fast analysis again (it worked in 3.0.5). Also will this work in V5 (a very compelling reason to upgrade :))?
Thanks in advance Sebastian
