 ## Segregation calculations in R and MATLAB
 **./R** or **./MATLAB**
 *  `segregation.R/.m`  -  calculates system segregation (Chan et al. 2014). 
-*  `segregation_by_type_prcont.R.m`  -  calculates segregation of specific system types (e.g., Sensory-motor, Association), and letting system of different sizes to contribute proportionally based on their size (# of nodes). This is a similar method to `segregation.R/.m` for whole brain system segregation. 
-*  `segregation_by_type_eqcont.R.m`  -  calculates segregation of specific system types (e.g., Sensory-motor, Association), but first averaging within/between system connectivity for each individual system. This allows smaller systems to contribute more to the overall segregation value of that system type. This was how system-type segregation was calculated in Chan et al. (2014).
