Hi, 

I got this error while running recon-all :  'imgreg_4dfp /opt/freesurfer-530/average/711-2C_as_mni_average_305 /opt/freesurfer-530/average/711-2B_as_mni_average_305_mask talsrcimg_g11 none talsrcimg_to_711-2C_as_mni_average_305_t4 1283' failed! status=254
ERROR: mpr2mni305 execution aborted

Any idea what could be the cause?

Thanks,
