Dear Afni Experts,
I want to do a very simple convolution, using 3dConvolve.
This is the command:

3dConvolve -input mean_iso_HRF+orig -num_stimts 1 -stim_file 1 4blocks_zeros_ones_for_convolution.1D -output Ideal_Block_Model

the input is a 3d+time dataset containing the hemodynamic response functions, the stim file is a simple column vector.
Below are the files involved, maybe it is of some help:
https://onedrive.live.com/redir?resid=4C8D30C2AD5C97AE!364&authkey=!AJNs-0rSF76VTq0&ithint=folder%2c.1D

I get the error message:
3dConvolve Error: Unable to open IRF file: (null)

is there something wrong with the BRIK file? when i open it in afni it looks completely normal.

Thank you for any help.....
