Firstly, when I try xhemi on pre-possessed longitudinal data, it showed error like this: Performing left-right swap of labels TR=2300.00, TE=2.98, TI=900.00, flip angle=9.00 i_ras = (-1, 3.72529e-08, 3.35276e-08) j_ras = (-2.6077e-08, -3.72529e-09, -1) k_ras = (-1.78814e-07, 1, 6.98492e-10) writing to /HD4/symptom_test//subj_02_1.long.s02_base/xhemi/mri/aparc+a seg.mgz...

ERROR: Are you trying to run or re-run a longitudinal time point? If so, please specify the following parameters:

' -long <tpNid> <templateid> '

where <tpNid> is the time point id (SAME as cross sectional ID) and <templateid> is the ID created in the -base run. The directory <tpNid>.long.<templateid> will be created automatically or used for output, if it already exists.

Secondly, how I can get the change rate after construct left -right registration.

Thanks, Lanbo
