External Email - Use Caution Thank you. Can you please clarify, documentation for mri_convert states default for resampling is -interpolate, does this mean trilinear? Also, which method is preferable for bbregister (I am applying it for intrasubject uni and multimodal registration), trilinear or cubic interpolation? I assume trilinear if that is the default, but cubic is listed in recon-all dev table in the -T2pial (multimodal) step, see below. Thank you again, Octavian
