[Mne_analysis] [Mne analysis] two sample t-test with spatio_temporal_cluster_test

[Talitha Ford]

Dear all,

Similar to conducing a pair samples t-test on source data using spatio-temporal clustering, allowing the visualisation of clusters where condition A > condition B and vice versa, is it possible to run an independent samples t-test to visualise differences between two groups? The 2 samples permutation tests currently available are limited in that they plot F statistics that don’t give a direction of the difference between the groups. Basically, is it possible to identify clusters that differ significantly between the groups, as well as identify/visualise the direction in which they differ? 

I am currently attempting to extract the cluster values for each participant to get an overall mean for each vertex within the cluster to compare between groups, but this seems very inefficient.

Cheers,
Talitha
