I guess it all depends on what "generating data" consists of in your case. If the nature of your role largely amounted to feeding inputs and collecting outputs in an experimental setup designed and created by your PI then maybe a footnote or an acknowledgement at the end of the article would be the most you could expect unless there are institutional rules in place that say otherwise; unfortunately, some PIs are more generous than others but there's nothing you can do about that. On the other hand if the nature of your role was significantly more than monitoring the experiment and overseeing inputs and outputs, you'd have a prima facie case. Some journals do have their own rules for attribution of authorship. I would contact the editor explaining your situation; just be polite and politic about it.

Aabid Hussain Ph.D

Well, here is a possibility. Since the abstract of that paper was already published in the conference proceedings with you as the first author, I would consider depositing the published abstract together with the full conference paper at an Open Access Repository.

Open Access Repositories allow you to deposit and share full research outputs, so for you it would provide some sort of record or acknowledgement of research priority, if not an actual publication. Better than nothing. ¯\_(ツ)_/¯

Aabid Hussain Ph.D You've drastically altered your question, deleted your accompanying explanation, and deleted all your own responses on this thread, the result being that my responses now lack a context and appear unmotivated. Not very ethical.

Karl Pfeifer, Sir, I deleted it by mistake; unfortunately, once I deleted my answer, I couldn't restore it. I am sorry, Sir.

It's about ethics, but those in power are the ones who decide; those don't need to follow ethics. So, I decided; instead of fighting for co-authorship, I would focus on building the future. I will try to consolidate all your answers into one message.

At night, my mind said to me; When you plan to stand on the peak of a mountain, sometimes you should step back before moving forward again. If you go straight ahead, that path may be harmful to you.
