write.ANALYZE(ttt, header=NULL, filename)

Arguments

ttt

4 dimensional datacube
header

header information
filename

file name

Details

Writes the datacube ttt to a file named file in ANLYZE file format. header is a list that contains the header information as documented by the Mayo Foundation. We give here a short summary. If a value is not provided, it will be tried to fill it with reasonable defaults, but do not expect fine results, if the entry has a special important meaning (h.i. pixdim).
