Linear regression on Time Frequency data

External Email - Use Caution

Dear MNE-team,

I'm trying to run a linear regression analysis on Time-Frequency data. I've got the average TFR for each for each subject and want to regress and individual difference measure on the time frequency data for a specific channel. The data has the same dimensions as for running linear regression on epochs but instead of channels I'm using frequencies. Unfortunately the linear_regression function provided by MNE does not allow TFR data as input. Is there a workaround for this problem? I would also like to run cluster-based permutation tests on the results of the linear regression to estimate significance. Would that be feasible?

Thank you very much for your help,

Sebastian

hi Sebastian,

can you step back and explain the overall aim of the procedure?
what would you like to show with your data? is it group level?
a contrast?

Alex
