I’m new to MNE. From Matlab I have 40 subjects’ data of 2 conditions. Each mat file contains a `419*400*33` matrix.  
I couldn’t find any example of how to run cluster permutation on time-frequency data.  
Most importantly, I want to know what kind of data array should I input to mne from my mat file in order to run it on mne permutation cluster.

please see this documentation page: [Creating MNE-Python data structures from scratch — MNE 1.6.1 documentation](https://mne.tools/stable/auto_tutorials/simulation/10_array_objs.html)

you can find some information by studying the docstring of the cluster permutation testing function here: [mne.stats.permutation\_cluster\_test — MNE 1.6.1 documentation](https://mne.tools/stable/generated/mne.stats.permutation_cluster_test.html)
