Hi FS Experts,

I'm trying to run a longitudinal analysis across three timepoints and have run the cross steps for the data. I then ran the base step but found that my voxel dimensions are slightly different across the timepoints and I got the following error

ERROR: MultiRegistration::loadMovables: images have different voxel sizes.
Currently not supported, maybe first make conform?
Debug info: size(2) = 0.881117, 0.881117, 0.881117 size(0) = 0.884507, 0.884507, 0.884507
MultiRegistration::loadMovables: voxel size is different /projects/pi-vokeane/HPC_16_00925/MC_FS_testdata_EOH/freesurfer/subjects/abd025_tp3/mri/norm.mgz.

I assume I need to resample the data to the voxel size of the first time point and then rerun. Can you advise on what command to use to resample the images from time 2 and time 3 to those of time 1 before rerunning from scratch. I assume I can't avoid rerunning the initial reconall step once I resample my data.

Any guidance is much appreciated

Best regards

Erik
