You can search recon-all.log for the command that generates those stats and appply it to the ?h.BA.thresh.annot instead of ?h.BA.annot. On Fri, 26 Jul 2013, Satrajit Ghosh wrote: thanks guys. any thoughts on when the ba*.stats files will use these? right now i agree with bruce that they are

There is a *.thresh.label version of all the BA labels in 5.3, but I don't think it's used by default. You can try using those labels instead. On Fri, 26 Jul 2013, Satrajit Ghosh wrote: hi bruce, currently 5.3, but the data i was looking at was processed with 5.1 and in that right ba44/45 wa

if it's not the thresholded version that might reflect the fact that it is less well-predicted and so the borders are more spread out Bruce On Fri, 26 Jul 2013, Satrajit Ghosh wrote: hi bruce, currently 5.3, but the data i was looking at was processed with 5.1 and in that right ba44/45 was al

Hi Laouchedi that is a big research question! The answer is a qualified yes, but it depends strongly on what labels you mean. In general we find that the closer you are to primary areas like V1/M1, the stronger the correspondence is. We do supply some explicit estimates of Brodmann areas, have
