Re: [Freesurfer] Questions re slice thickness, aseg and longitudinal analysis

2019-10-09 Thread Martin Reuter
Hi David, I am not very optimistic: 5mm is too thick for FreeSurfer (recommendation is 1 up to 1.5). You will certainly get something, but it can be very unreliable and completely wrong. Especially longitudinally these thick slices will induce large variance due to different head positioning

Hi James I think the -lh/-rh flags are for processing single (ex vivo) hemis, not for only processing one hemi in a whole-brain image. If you want to erase the hemi with the tumor it will probably work cheers Bruce On Wed, 9 Oct 2019, 王子谦 wrote: External Email - Use Caution

Hi Ezequiel -noscale 1 works in most cases, but here the analyze file itself specifies a scalling that is done as part of the reading process. If you want to disable it try (in tcsh): setenv FS_ANALYZE_NO_RESCALE 1 then run mri_convert as before. You should see an addition printout in the
