Dear FSL Experts,
Sorry to bother again about my question about TBSS_3_postreg with cutoff of the top of the brain (posted 1.12.2010). I was wondering if the problem could be related to the sample size (184 in total divided equally between two groups) when using -n option in the tbss_2_reg step. As this takes quite a while to run I was hoping someone may be able to point me in the right direction before I try to rerun the process again as I haven't changed anything from a successful run to this analysis with the top of the brain cut off apart for the sample size.
Any suggestions greatly appreciated.
Thanks and again sorry for the second post.
Kind regards
Erik
