When should I debayer my masters???

[dcastroimage]

I have an STL 11000cm OSC and I'm making master dark,bias and flats. When should I debayer if at all. Could someone explain the process to me in steps please? And for that matter, when should I debayer my lights? Before calibration or after integration? Thanks!

never debayer the flats, bias or darks

for lights,

calibrate -> cosmetic correction (optional) -> debayer -> register -> integrate
