[FieldTrip] One-sample T-test with cluster-based statistics at the group-level

[Andrea Brovelli]

Dear all,

I'm sorry to insist on this issue which has largely discussed on the 
mailing list 
(https://mailman.science.ru.nl/pipermail/fieldtrip/2018-October/025301.html) 
(https://mailman.science.ru.nl/pipermail/fieldtrip/2018-August/012314.html), 
but I cannot find an easy way out to perform a one-sample t-test with 
cluster-based statis at the group (or single subject) level using Fieldtrip.

As you are probably aware, MNE-python has implemented such test in this 
code 
<https://martinos.org/mne/stable/generated/mne.stats.permutation_cluster_1samp_test.html> 
starting from the fact that [lines 1182-1186]:

"Because a 1-sample t-test on the difference in observations is 
mathematically equivalent to a paired t-test, internally this function 
computes a 1-sample t-test (by default) and uses sign flipping (always) 
to perform permutations. This might not be suitable for the case where 
there is truly a single observation under test"

Is there a way to "hack" the current version of Fieldtrip to perform 
such test?

Are you planning to implement it in the near future?

Thanks a lot.

Cheers,

Andrea
