Dear folk:
I have some questions about the PCA plot in the MELODIC results report. In the MELODIC report folder, there is a html file showing the ICA analysis results. If opening the html file, one will see a PCA plot report with 3 curves(red, green blue) on it.
First of all, is the x-axis and y-axis in the plot means the number of eigenvalues and the value of eigenvalues respectively? Also, as the plot says, the red curve means dimention estimate and the green one means percentage of variance. I am just confused on how to understanding the red and green curves in the plot. For example: the maximum y-value on my PCA plot is 1.05, but my projected subspace is 42-dimentional. Then, how should I explain the red curve in the plot, as well as the green one?
Thanks alot
Xuelin
