Hi I would like to know what does signature column means in a differential gene expressed result??what do u interpret by its values TRUE or FALSE ?? So please help me out Thanks

'Signature' is an unfortunate choice of word. If it is TRUE
, it means that the gene is statistically significant at the default p-value threshold of 0.001. The Signature column, therefore, just provides for an easy filter.

i got the data from GEO, the study is based on understanding the differential expression of RNA transcripts and proteins. micro-array and mass spectrophotometry was used to analyze . I used DEGseq to find the Differential expressed genes but there is one columns(SIGNATURE) in the table which i was unable to understand . what is the significance of the signature values true and false? what do you interpret if the signature is true or the signature is false?
results:

Thanks - please see my answer, below
