Which version has FFT enabled?

Roofit and RooStats

Dear Experts

I am using a Tag&Probe package in CMSSW. In this package for fitting I am using a convolution class RooFFTConvPdf but it requires root to be enabled with FFT(Fast fourier transform).

I would like to know which version of root has FFT enabled so that I can install root from cern afs.

Thanks in advance.

Hi,

Most (if not all) the newest version of ROOT on CERN’s afs should have FFT enabled. In recent version of root you can also double check by running:root-config --feature

Cheers,
Philippe.
