Dear Experts, 

As an addendum to the last post I made here are the commands I propose to use to extract lobar measures for GM and WM. I would be grateful for input.  

GM Lobar Values

(1) mri_annotation2label --subject subject1 --hemi ?h --lobesStrict lobesfile

(2) mri_anatomical_stats –mgz –cortex  ../label/?h.cortex.label –f ../stats/?h.lobesfiles.stats –b –a ../label/?h.lobesfile.annot subject1 ?h white

Q: Is this valid?

Q:Do I need to include that part of the command in italics - is it not redundant given the use of the ?h.lobesfile.annot - using one or the other does give a different result at the top of the stats file (namely NumVert, WhiteSurfArea, and mean thickness which disappears if ?h.cortex.label is not passed) - why is this ?

WM Lobar Values

(1) mri_annotation2label --subject subject1 –hemi ?h --lobesStrict lobesfile

(2) mri_aparc2seg --s subject1 --labelwm --hypo-as-wm --rip-unknown --volmask --o mri/wmparc.lobar.mgz --ctxseg aparc+aseg.mgz --annot ?h.lobesfile.annot

Q: Is this valid ?

Q: Do I need all the items in italics - they are present in the recon-all logfile but not in some forum posts on similar topics.

(3a) mri_segstats --seg mri/wmparc.lobar.mgz --sum stats/wmparc.lobar.stats --pv mri/norm.mgz --empty --excludeid 0 --excl-ctxgmwm --supratent  --subcortgray --in mri/norm.mgz --in-intensity-name norm --in-intensity-units MR --subject subject1 --surf-wm-vol --surf-ctx-vol --totalgray --ctab newcolourtable --etiv

OR

(3b) mri_segstats --seg mri/wmparc.lobar.mgz --sum stats/wmparc.lobar.stats --pv mri/norm.mgz --excludeid 0 --brain-vol-from-seg --brainmask mri/norm.mgz  --in mri/norm.mgz --in-intensity-name norm --in-intensity-units MR --subject subject1 --surf-wm-vol --ctab newcolourtable --etiv 

Q: Which of these should I be using - the latter is based on the recon-all log file, while the former is based on forum posts - what are the differences (as highlighted in italics).

Thanks.
