Hello,

I got an error information as below:

** FATAL ERROR: -matvec file not a 3x4 matrix!
** Program compile date = May 21 2017
** ERROR: Could not oblique/shift anat to epi data

I checked the matrix using in the code, it is a 3*4 matrix. Well, at least it contains 12 numbers.
Here it is:
# 3dAllineate matrices (DICOM-to-DICOM, row-by-row):
1.00309 -0.0030288 -0.00490386 -0.45253 0.00511126 1.00771 0.00498307 -1.09497 0.00639334 -0.00971128 0.991483 -2.43748

So I don't understand what the problem is. Please could someone help with this?

Many thanks,
Sarah
