Included folders and files are:
- article_figures: all figures published in the manuscript and in the supplementary document (.svg format)
- experimental Data: .fid files of the MRI measurements ordered, the script for comparison of methods and supporting files (ROIs and masks), and corresponding mono-exponential fitted T1 rho maps.
- macro_files: VnmrJ macro files for setting up the measurements using all the pulse schemes discussed in the manuscript and supplementary documents.
- RF_Pulse_sequences: VnmrJ RF waveforms used in the study, generated using the included Matlab functions
- matlab_functions: Matlab functions used for creating the RF waveforms (T1rho pulse schemes) and for data analysis with subfolders and files:
    - aedes_plugins: plugins for aedes (http://aedes.uef.fi) and scripts to read all raw data files for calculation of relaxation time maps     - miscellaneous_functions: Pulse generation functions and other functions (Pulse generation, sequence reading and display,                and pulse simulation scripts) and also scripts for RMS calculation.
    - PulseTrain_Generator.m: GUI tool for using the various included scripts for creating the RF waveforms used in the study
