To quantify the percentage of FA asymmetry for a tbss_sym analysis (L-R and R-L), I would like to use the laterality index (LI=NL+NR/ NL−NR), as suggested by one of the astute FSL experts. The simplified formula syntax should be LI=L+R/L-R. Is this correct?
I did both L>R and R>L analyses and I am uncertain which utility and utility syntax would be best to extract and calculate the LI information.
Any recommendation would be much appreciated
