[Homer-users] R-values

[Yucel, Meryem A.]

Hi Jonathan,

R in the procresults is the correlation coefficient of the GLM fit to the data i.e. the whole time course so including all conditions. So its dimensions are # of channels X Hb (HbO and HbR).

Hope this helps.

Does anyone know what the R value in the ProcResult is 2-dimensional?  It shows it to be (#channels, HbO/R/T).  Why are the number of conditions not included?

For the beta values, the structure seems to be (coefficients, HbO/R/T, #channels, #conditions) which makes sense.  Why is it the R-values don't match this?
