That is indeed one way to find the mean. If you have many images you may want to use the "Yes read data into data matrix" option if you have done this then you can use mean(X) instead.

Hi all,

I am working with ImCalc and I would like to know if I can do a mean functional image of 2 functional independet components?

(i1+i2)/2 - Would the output be the mean activation patern of components 1 and 2?

Thanks for all the help,

Jose
