Hi,
Both the Zscr and the one sample ttest problems are on my end...
It never occurred to me to look at a one sample test with box plots, but it makes total sense.
I may have left it out because I haven't yet added support for covariate files.
The error caused by the program looking for 2 labels for the 2 groups in the case of 3dttest++
I can try to get fixes in over the weekend.
The Zscr fix should be easy.
The one sample fix may take a little testing, as it may break other shiny things.
Thanks, Justin
