Thanks Bruce! Those are the main questions now (not only to V1, but also to the rest of the Brodmann areas). I really want to be sure where the measures come from. I want that the different measures (i.e. cortical thickness and area are really from the same region in the cortex), to know what should be exported to run the statistical analysis.
At some point the list email was not in Cc anymore... Here it goes to the list too.
Thank you so much for your help!

where do the V1 stats in the stats dir come from? What binary and what surface?

sorry, what is the question?

I'm not sure where the stats dir output comes from, Doug would know. The others seem reasonable, and certainly the pial should be bigger than the white. We also generate a couple of V1 labels, one from the Hinds atlas and one from the Zilles labels I think, although maybe the Hinds one isn't generated by default anymore. Nick can answer that question.
Also, please cc the list on these emails! You will get a faster response time and the right people will be able to help you

Hi Bruce!
Ok!
In fact I've already tried to use 0 as threshold, here's what happens:
surface area from
- stats directory output: 2081
- label_area -t 0 -s white rh S11 rh.V1: 2840.946
- label_area -t 0 -s pial rh S11 rh.V1: 3509.024
That's way too different. Using label_area is given higher values. Why? Could this have something to do with the substitution of the label_area file? This would mean that at some poit recon-all used the previous one to generate the output of the stats directory?
Since pial and white surfaces usually do not follow exactly the same shape and, thus the same area (since there are different thickness in between) , I'm antecipating reviwers questions of things like "from what surface are you reporting the values?"
Cheers, Andreia

Hi Andreia
did I say use 1.1? If I did, I'm sorry and take it back. 0 would give you all the vertices in the label (this is the default). 1.1 would give you an empty label since nothing would pass that threshold.
I wouldn't worry about thresholding the aparc boundaries, as there we want a complete parcellation of the cortex, so if you took it out of one parcel you would have to give it to another (less likely) one.
cheers Bruce

Sorry now I'm confused. I understood you said that I should try 1.1 as threshold. Anyway, this means that the values in the outputs from the stats directory do not take into account any threshold. Thus, the surface area given is from the bigger probable area no matter how unlikely all the points belong to it, correct? Could this be a problem when interpreting results using cortical thickness, surface area and/or volume of the studied regions?
And concerning the aparc areas, is the ideia the same?
I'm sorry to be insisting on this but I need to know what is the meaning of the values I'm using, principally because when discussing measures like these one must be carefull, as you know :)
Thanks!! Andreia
