Slightly different results when implementing spin_test in MATLAB vs. Python

[Melissa Thalhammer]

Dear Enigma toolbox users,

I have implemented spin_test() in Matlab and Python and have noticed some little differences in p-value... Has anyone noticed that before?

I have attached the data I have worked with if you want to try it:

- expression_brainorder.csv: gene expression across 68 Desikan Killiany regions obtained and preprocessed via the abagen toolbox

- workflow_matlab2.m in Matlab2021b: reads in my custom gene data preprocessed with abagen, uses random cortical thickness data, performs spin_test in addition to "normal" spatial Spearman correlation, and adjusts p-values for multiple hypotheses testing

- workflow_python.ipynb, a Jupyter Notebook doing the same

I'd appreciate any feedback since I am also not as familiar with Matlab, thank you!! :)

Best, Melissa
