Hi,
I am running some data given to me by a prof through FEAT to see if I get the same results as he did (in SPM)
I noticed in the FEAT log this message that said error under zstat4, this is exactly what it was, note the error at bottom:

...and then it continues on and finishes without any kind of alert or anything
Is this something I should be concerned about? So far my subjects have shown very little to no activation in the fourth contrast set up, is this from an error?? (However, I was not expecting much activation for this 4th contrast).
Any comment on this would be great.
Thanks
Aaron
