Hi, thanks for this great tool. I got a error when I call TRESS_DMRfit function for differential peak analysis, here is the error information:

DMR.fit = TRESS_DMRfit(IP.file = IP.file,
                       Input.file = Input.file,
                       Path_To_AnnoSqlite = Path_sqlit,
                       variable = variable,

                       OutputDir = OutputDir,
                       experimentName = "DOXvsDMSO")

In addition: Warning message:

  Make sure to always combine/compare objects based on the same reference

Thanks for your help!

I see the same problem on Windows. Is there an option not to use it (mc.cores)?

Sorry for my long-delayed reply. We have just updated TRESS to make it compatible with Windows. Please download the latest development version TRESS 1.7.1. Thank you again for trying TRESS!
