begin script to create difference maps, determines whether each voxel is affiliated one or many networks
gets index and value of max stat for each voxel
broadcasts data array to 2D and takes mean difference between primary net and all others
moved functionality to functions. corrected the way max values are masked from non-primary array
function to calculate difference map for subject is working
add lines to save to nifti image, added if main statement
fixed nibabel import and print statement
fixed subid pattern
begin adding functionality to create summed difference maps and scaling
added in functionality to create image of difference between primary net and sum of all other networks
