Matlab code to visualize power spectra on head movement regressors as reported on the manuscript “Correction of respiratory artifacts in MRI head motion estimates”, Neuroimage.
Repo location: https://github.com/DCAN-Labs/movement_regressors_power_plots/
Here we release four utilities. Each one has their one documentation, example(s) and data. The utilities are:
-
cat_mov_reg_power: This function concatenate the relative contribution of power of each frequency band from multiple subjects.
- Documentation:
01_to_run_cat_mov_reg_power.pdf
- Documentation:
-
power_per_Resting: This is a companion figure to cat_mov_reg_power. It shows the power spectra from each movement regressor.
- Documentation:

- Documentation:
-
get_peaks_from_movement_regressors: This function identifies the peak in the spectrum.
- Documentation:
03_to_run_get_peaks_from_movement_regressors.pdf
- Documentation:
-
aliased_RR: This function displays a table with the aliased frequency (in Hz) of a signal provided in events per minute (RR_bpm). You also need to provide the TR in seconds.
