Hi,

I am having some trouble in retrieving the results of a Differential Analysis using Diffbind. In particular, when I use the function

dba,report()

with the option bflip=TRUE or FALSE I do not see any change in the output in the field of the fold. I see a change of the column order regarding group 1 or 2 however not the fold in sense of direction of change. I can understand the values of Concentration Group 1 or 2, but not the fold, because I cannot reproduce using Group1 - Group2

as an example I write down one line of the table

Conc_a_POS Conc_NEG Fold 1,649371384 9,22688822 6,20142525

from those values: 0 5,76 3,65 # group 1

Thanks a lot if you can help me to solve

Michela

This was previously reported as a bug and fixed in version 3.2.4, so it works in the latest version of Bioconductor.

There is a workaround for version 3.0.x, which is to set the baseline for the contrast using the reorderMeta parameter of dba.contrast(). This is actually better practice -- bFlip is somewhat obsolete since version 3.0 enabled arbitrary design formulae and control of the ordering of factor values.

Hi, thank you so much!

I apologize for late answering.

I'm going to update Bioconductor and follow your always kind follow up and suggestions. Hope I would be able to solve.

Thanks again,

Michela
