Without the t-shifting and detrending (using the original oba.slibase.1D instead):
file_tool -test -infile oba.slibase.1D -->
oba.slibase.1D has 0 bad characters
oba.slibase.1D file type: UNIX
1d_tool.py -show_rows_cols -infile oba.slibase.1D -->
rows = 153, cols = 1950
and when I rerun my afni_proc.py, I get a similar error with different values:
** ERROR: ricor nsliregs x nslices != nvec (45, 43, 1950)
(150 ricor slices, 43 volume slices, 13 slice 0 labels)
