Lack of a systematic strict supervision has lead to inaccuracies in data evaluation. This data was published. While writing thesis I realize that and I don't know what to do. Should I write my "reanalysis" of published data in PhD chapters and explain, what was done incorrect and limitations of the interpretation? Or should I issue errata on the published materials (which is a red flag for thesis and following defense)?
I have learned my lesson for future and will be more accurate and precise. I do realize that it is the main stone of a good scientific practice. But now I just failed. I feel that I need an advice of what to do with an actual situation to reach defense and be able to complete PhD studies?
