I’m happy to see that FreeSurfer6 provides enhanced support for slice timing. I’m trying to run it on some multi-slice data. May I ask you for some guidance on how to use the new preproc-sess options? As I understand it, I would specify “-ngroups 10” because the data were collected in ten groups of six slices at a time? I’m not sure how to specify “-sliceorder”. Slice times are below. Thanks for any help you can provide.
