External Email - Use Caution

Hi,

In Tracula Wiki, there is a slice of displaying P-values for T-test on differences in mean FA/MD/… between groups following this link and sample plot attached below.

https://ftp.nmr.mgh.harvard.edu/pub/docs/TraculaNov2013/tracula.workshop.iii.pdf.

I want to know what is the command for this and is there a useful link to demonstrate the process?

Thank you so much!

Best,
