- A program to compare voxel values in two 3D NIFTI files.
You give pixelcomp two files, each with their own mask. Any voxel that has a nonzero mask in both files gets added to a list of xy pairs, with the value from the first file being x, and the value from the second file being y. Pixelcomp then: 1) Makes and displays a 2D histogram of all the xy values. 2) Does a linear fit to x and y, and outputs the coefficients (slope and offset) to a XXX_linfit.txt file. 3) Writes all the xy pairs to a tab separated text file, and 4) Makes a Bland-Altman plot of x vs y
Two 3D NIFTI image files, the accompanying mask files, and the root name for the output files.
