What are those predefined spheres?

Submitted by phil1022 on

Dear Chao-Gan,

    In your most recent version of DPARSFA, you added a new version of templete. In this new templete, once clicked in the Define ROI interface, there are a lot of predefined 5 mm sphere ROIs along with AAL and other ROIs.

    I did not pay attention to them at begining which turned out to be over 70 G of masks when I selected "wrap back to native space".

    Anyway, I do appreciate predefined spheres that can help us unify analysis accross studies. However, you did not provide a list of discription of these spheres which makes them useless. I don't really know how to utilize them efficiently. By finding a particular sphere may be more difficult than define one by ourselves.

    I'd like to see your opinion on this.

    Thanks for providing such a powerful tool.

    With kind regards.

    Sincerely,

    Xiaosong

Hi Xiaosong,

Those sphere ROIs were defined by  Dosenbach et al. (2010). Dosenbach, N.U., Nardos, B., Cohen, A.L., Fair, D.A., Power, J.D., Church, J.A., Nelson, S.M., Wig, G.S., Vogel, A.C., Lessov-Schlaggar, C.N., Barnes, K.A., Dubis, J.W., Feczko, E., Coalson, R.S., Pruett, J.R., Jr., Barch, D.M., Petersen, S.E., Schlaggar, B.L., 2010. Prediction of individual brain maturity using fMRI. Science 329, 1358-1361.

Those preselected masks are utilized for a big data sharing initiative, i.e., preprocess all the open R-fMRI data, as well as provide a platform for all the researchers share their R-fMRI maps processed by a standard procedure with DPARSF.

We will release a minor revision of DPABI soon, by add a button "Remove all ROIs" in the ROI setting panel.

Given your feedback, we might consider to remove the Dosenbach 160 ROIs from the preselected list.

Best,

Chao-Gan
