Synopsis

mri_concat.bin

Arguments

Optional Flagged Arguments

--o out

Output

Input

--f listfile

List file has a text list of files (up to 40000)

--paired-sum

Computes paired sum (1+2, 3d+4, ect.)

--paired-avg

Computes paired average (1+2, 3d+4, ect.)

--paired-diff

Computes paired difference (1-2, 3d-4, ect.)

--paired-diff-norm
