Added new function of "corr(i1,i2,'spatial')" in REST Image Calculator. (DONG Zhang-Ye)

Submitted by insular on
Dear Dr. Dong

I notice a new function added into REST Image Calculator, "corr(i1,i2,'spatial')" .

What is the 'spatial' correlation between image 1 and image2?

Is there any ref. about this  'spatial' correlation?

Thanks.

Hi,
Since Dr. Dong has graduated, he may not notice this message.

Here, I'll try to explain  "corr(i1,i2,'spatial')".
Image i1 has a number of voxels with different values. They could be considered as a time cource (e.g. TC1).
Image i2 has a number of voxels with different valuse. They could be considered as a time coures (e.g. TC2).

"corr(i1,i2,'spatial')" is the Pearson's correlation analysis between TC1 and TC2.

Hope this is helpful to you!
