I am running a VBM analysis in FSL. I have searched on the JISC Mail archives for solutions to this error but have had no luck. I have a lot of available space on my laptop, so it is not a space issue. I have also had this problem across multiple Mac systems. Any help will be greatly appreciated, I have been struggling with this for days.

When I run the code "fslvbm_2_template -n" I am expecting to create a file named template_4D_GM but get this error code in the output:

to check general alignment of mean GM template vs. original standard space template.

When running "fslvbm_2_template -n" I find that fslvbm2a and fslvbm2b will run without error but I hit the problem at fslvbm2c. When I run this specific piece of code from the fslvbm_2_template - FSLVBM template creation (http://ftp.nmr.mgh.harvard.edu/pub/dist/freesurfer/tutorial_packages/OSX/fsl_501/bin/fslvbm_2_template):

I had the same problem and when debugging I found out that the problem was in the line 94 T=${FSLDIR}/data/standard/tissuepriors/avg152T1_gray (in fslvbm_2_template). The problem is that this image (used as template) is a .hdr but it needs to be a nii.gz to be readable by the program. So, the solution is to download an avg152T1_gray.nii.gz and replaced the .hdr image for the new one. I changed the avg152T1_gray.nii.gz name to avg152T1_grayNI.nii.gz and copied it into the same folder (tissuepriors).

#T=${FSLDIR}/data/standard/tissuepriors/avg152T1_gray (commented .hdr image that don't work)

T=${FSLDIR}/data/standard/tissuepriors/avg152T1_grayNI (.nii.gz image that works fine for me)

I solved the problem by making fslreorient2std - to all NIFTI images before doing the template_list (STEP 1 in FSLVBM Analysis). I think this tool make the correct orientations so that fslvbm_2_template can read in a fast and easy way each image in order to average them with the avg152T1_gray template.
