Hi,

I experienced a failure while running align_epi_anat.py; the screen output follows this message. The problem seems to be with the version of 3dvolreg that the script ran, specifically with the -1Dmatrix_save flag. However, I don't think our 3dvolreg should be out of date--we just installed the latest Linux xorg7 64bit package from the AFNI website, and

> which 3dvolreg

returns the path to this latest installation. Please let me know if you can make sense of this.

Thanks,

Jeff

The intensity in the output dataset is a modified version
of the intensity in the input volume.
To obtain a masked version of the input with identical values inside
the brain, you can either use 3dSkullStrip's -orig_vol option
or run the following command:
3dcalc -a __tt_121908.mprage+orig -b __tt_121908.mprage_ns+orig -expr 'a*step(b)' \
-prefix __tt_121908.mprage_ns_orig_vol
to generate a new masked version of the input.
