[Eeglablist] SIFT resampling surrogate distributions with 1 trial

I'd like to use a resampling technique (e.g. bootstrap) to get p-values and
test stats for SIFT connectivity metrics for 1 subject across n conditions.
This is a steady-state condition study, hence there's only 1 trial per
condition. I'm trying to analyze whether certain connectivity metrics
(i.e. their averages over a condition) are statistically significantly
different across the conditions. I was under the impression I could use
SIFT's surrogate distribution generator to obtain the surrogate
distribution for these calculations, but when I run that from the GUI for
bootstrap, I get the error:
"Unable to compute bootstrap distributions for a single trial"
Is this surrogate function only designed to do boostrapping over trials? Or
is there a way to do it over windows within a condition?
