Hi Jürgen
You can get more information about each subject's ROIs using the flag "--report-rois". I need to tidy it up a little but it will say i) what ROIs current subject has which no other subject has. ii) what ROIs this subject lacks which atleast one other subject has.
Maybe, it'll be helpful?

Hi Krish
I do not really understand this behaviour. It seems, at least for my data, that the UNION is always 78, irrespective of the number of subjects (single subject, 10 subjects, 50 subjects, 104 subjects) subjected to the aparcstats2table command. This is also the case for 48 additional subjects from another study. It seems that each single subject of the 104 has a maximum of 78 parcellations (of course, some of them have less than 78 as indicated by zeros).
Is this what you would expect when made a UNION across several subject numbers (different single subjects, 10, 50, 104)?
Thanks for clarification Regards Jürgen

Hi Jürgen
The default behavior of the rewritten aparcstats2table is it takes the UNION of all the parcellations and writes them to a table. For instance Suppose subject sub1 has parcellations parc1 and parc2 and subject sub2 has parcellations parc2 and parc3
the union of parcellations is parc1, parc2, parc3. so the written table will be like
lh_aparc.a2005s_volume parc1 parc2 parc3 sub1 <some value> <some_value> 0.0 sub2 0.0 <some_value> <some_value>
As Bruce said, all parcellations may not occur in a given subject, so if you think the union of the all the parcs in all subjects exceeds 78 areas, let us know.

Dear FS experts
There are 94 surface labels listed in the surface_labels.txt file in the FS home directory. However, when using aparcstats2table with the --parc option aparc.a2005s there are only 78 parcellated areas per subject reported in the list.
Why?
Thanks Regards Jürgen
