Solar g modes have been the object of a long quest and their detection by one group (Garcia et al. 2007) still waits for confirmation (Appourchaux et al, in press). Several analysis methods have been used for this quest. We propose here to review and test these different methods (simple Fourier analysis, collective search in the "spectrum of the spectrum", correlation with expected frequencies...). The efficiency of these methods will be tested and compared using simulated data, before an application to real data (mainly from the GOLF instrument).
