Based on the current formulation of the FDR, datasets having high decoy scores can lead to FDR values > 1 leading to loss of some annotations when preparing results by applying a cutoff of FDR < 1 (

result_df = result_df[(result_df.msm > 0) & (result_df.fdr < 1)]
).

This fixes the FDR calculation by adding the weighted decoy term to the denominator as well to make sure that FDR is always [0-1].
