I/O functions

Write BRIK/HEAD files.

write.AFNI(filename, ttt, label = NULL, note = NULL, origin = NULL, 
               delta = NULL, idcode = NULL, header = NULL, taxis = FALSE)

Arguments

filename	name of the file
ttt	datacube
label	labels (BRICK\_LABS), depreciated - see header
note	notes on data (HISTORY\_NOTE), depreciated - see header
origin	origin of datacube (ORIGIN), depreciated - see header
delta	voxel dimensions (DELTA), depreciated - see header
idcode	idcode of data (IDCODE\_STRING), depreciated - see header
header	This is a list of header information such as DATASET\_RANK to be written to the .HEAD file. Arguments label, ... are depreciated and to be substituted by a corresponding list entry. For backward compatibility the use of the old arguments is still supported and should give the same results. This will be removed in some future release! Since AFNI does not read any dataset with a header choose carefully what is written. There are some basic tests in this function, but this may not be sufficient.
taxis	logical (defaults to FALSE. Are the sub-bricks time series? This results in writing TAXIS attributes to the header file.

Details

Write out BRIK/HEAD files as required by AFNI. Most arguments correspond to entries in the HEAD file, but use is depreciated. Use header and taxis instead!

Value

Nothing is returned.
