Hi folks,

Wanted to use @SSwarper outputs with afni_proc, per @SSWarper instructions. Running into an issue during testing. This subjects completes just fine if I run nonlinear warping in the afni_proc pipeline, but when copying from @SSwarper I receive the following error

cat_matvec -ONELINE anatQQ.sub-8035ctbs_WARP.nii anatQQ.sub-8035ctbs.aff12.1D
cat_matvec: malloc.c:2394: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.

This was in the warp anat follower datasets (affine) section, specific command called:

# -----------------------------------------
# warp anat follower datasets (affine)

# catenate all transformations
cat_matvec -ONELINE                                                         \
           anatQQ.sub-8035ctbs_WARP.nii                                     \
           anatQQ.sub-8035ctbs.aff12.1D > warp.all.anat.aff12.1D

The application of the warps worked fine on the EPI data, just seemed to hit a snag with the anat_followers and failed at the first step of that section. Any ideas?

I would also like to note that the help for @SSwarper is slightly misleading, in that it states you need to do the following:

-tlrc_NL_warp                                                   \
    -tlrc_NL_warped_dsets                                           \
       anatQQ.${subj}.nii                                           \
       anatQQ.aff12.1D                                              \
       anatQQ.${subj}_WARP.nii

The second dset should also include $subj, as in anatQQ.${subj}.aff12.1D. I note this, because I first copied and pasted this section and it failed because I had incorrectly pointed towards a nonexistent 1D file
