Hi,
I am running 3dDeconvolve with the -no data option to create an optimal timing sequence. The script will run 3dDeconvolve through 100 iterations of the waver file. I am getting the following error messsage:
++ 3dDeconvolve: AFNI version=AFNI_2008_07_18_1710 (Apr 15 2009) [64-bit]
++ Authored by: B. Douglas Ward, et al.
++ using NT=257 time points for -nodata
*+ WARNING: Input polort=1; Longest run=257.0 s; Recommended minimum polort=2
Matrix error: Unable to read matrix from file: contrasts/contrast_hivslo_const
** Memory usage: chunks=91 bytes=49991
read_glt_matrix
read_input_data
initialize_program
3dDeconvolve main
Invalid null command.
The contrast file: contrast_hivslo_const is set up as follows:
0 0 1 1 1 1 -1 -1 -1 -1 1 1 1 1 -1 -1 -1 -1
If you could let me know how to fix this error, I would appreciate it.
