Hey folks,

I'm trying to use 3dNwarpApply to combine multiple transformations in a single step. I'm using the version compiled on Dec 5 2014, and I think the recent update might have broken my script. Previous versions of the script worked, now I am getting the following error.


Processing -nwarp ** ERROR: Cannot read affine warp from file '018.base_PLUS_al.1Dparam.1D'

This comes from the following command:

3dAllineate \
-warp shift_rotate \
-1Dparam_save ${subject}.base_PLUS_al.1Dparam.1D \
-base ${subject}.anat.fs_ss+orig \
-source ${subject}.base_PLUS+orig \
-prefix ${subject}.base_PLUS_al

I've verified that the file does exist, and that it contains the following transformation parameters.

# 3dAllineate parameters:
# x-shift y-shift z-shift z-angle x-angle y-angle
-0.614628 13.531715 -20.516838 -3.949078 15.605938 -2.711121

For reference, here is my 3dNwarpApply command.

3dNwarpApply \
-nwarp "${subject}.base_PLUS_WARP+orig ${subject}.base_PLUS_al.1Dparam.1D ${subject}.anat.fs_ss.qepi_WARPINV+orig ${subject}.anat.fs_ss_Allin.aff12.1D ${subject}.anat.fs_ss_WARP+tlrc" \
-master ${subject}.anat.fs_ss+tlrc \
-source ${subject}.buck+orig \
-prefix ${subject}.buck.qwarp

Thanks,
