It looks like you need to specify the name of the transformation matrix that
is to be output, in addition to the output filename of the transformed
image.
Peace,
Matt.

Subject: [FSL] FLIRT input error?
Hello again. I am new to fMRI and to FSL, so forgive me if this is an
ignorant question, but in
FLIRT, (using the feeds data to learn the system) it defaults to a reference
image of:
/Users/MLE/fsl/data/standard/MNI152_T1_2mm_brain
What do I put in for an input image? I assume that I want a structural, so
I was using
/Users/MLE/Desktop/FSL/feeds/data/structural_brain.nii.gz
and I assume as well that it should default to some output image? I.e., I
don't put that in myself?
When I hit 'go', it gives me this error:
/Users/MLE/fsl/bin/flirt -in
/Users/MLE/Desktop/FSL/feeds/data/structural_brain.nii.gz -ref
/Users/MLE/fsl/data/standard/MNI152_T1_2mm_brain -out -omat .mat -bins 256
-cost corratio
-searchrx -90 90 -searchry -90 90 -searchrz -90 90 -dof 12 -interp
trilinear
WARNING: change in option usage
To specify the input volume the option -in should be used
Accepting the filename for now, but please update to new syntax in future.
** ERROR (nifti_image_read): failed to find header file for '.mat'
** ERROR: nifti_image_open(.mat): bad header info
Error: failed to open file .mat
ERROR: Could not open image .mat
Image Exception : #22 :: Failed to read volume .mat
terminate called after throwing an instance of 'RBD_COMMON::BaseException'
Finished
A) am I using the wrong images? If so, what images am I to use?
B) What does this error mean?
C) could it be that it doesn't like the length of the filename? That it has
to go too deep for the
data (through too many folders)?
Thanks!
Emily
