Hey AFNI experts,

I have basically posted this exact question once before. My afni_proc.py script kept dying during one of the warping stages (applying warp using 3dNwarpApply) giving me a Fatal Signal 6 (SIGABRT) received and a memory corruption message.

We figured out it was due to a large distance between the anatomical and functional datasets. The problem was solved by running @AlignCenters on the functional and anatomical datasets using TT_N27 as the base.

I recently got some data from another laband I basically get identical error messages and linear warping warns me about the data sets beeing far appart. I have tried to allign the centers using @AlignCenters and I use the -ginormous_move option. This still fails me. What should be my next move?

My analysis

@Align_Centers -base ~/abin/TT_N27+tlrc. -dset TEST_sT1W_3D_TFE_SENSE_4_1+orig. -child TEST_Risk_SENSE_8_1+orig.
