I'm using diffbind to identify differential binding of CUT&tag peaks of H3K27ac. I obtained scaling factors from ChIPSeqSpikeIn package. I'm very new to bioinformatic analysis. I know the Diffbind has dba.normalize function which you can specify a numeric normalization factor. Could anyone suggest the code to specify number for normalization method in dba.normalize using DiffBind? Thank you so much.
