Hello,

I am having a problem with using @auto_tlrc. The individual subject's Talairach anatomical image is appearing larger than the TT27 template. Therefore, the alignment of the CC and other structures are off. I am trying to warp children's anatomical images to the standard adult talairach template. I am unsure how to fix this issue. I've tried to upload a jpg but the image attachment isn't working. Below is the code that I am using (I have tried to use xform shift_rotate_Scale and init_xform AUTO_CENTER both separately).

align_epi_anat.py -anat2epi -anat t1mpragesagp2isos002a1001+orig \
-anat_has_skull no \
-save_skullstrip -suffix _al_junk \
-epi min_outlier_volume+orig -epi_base 0 \
-epi_strip 3dAutomask \
-volreg off -tshift off
