Figshare gives free DOIs to the uploaded papers: https://figshare.com/

mee too, i have the same problem.

use this link

If you manually upload the paper on ResearchGate, it will generate a DOI for the uploaded paper automatically.

No,you should pay some thing

But when you upload your Research paper to Research Gate ,they will provide a DOI free of cost.

Can some one explain step wise how to get doi for an article uploaded manually to research gate?

Recently i have tried for the same but there was no option to generate doi !!

I have followed the instructions given here https://explore.researchgate.net/display/support/ResearchGate+DOIs

Hi sir i believe if its an article published elsewhere and a DOI obtained by that publisher you will not be able to generate one new.instead you can cite the same DOI.if the article is not published then you can generate one for yourself....

Go to Add research in research gate and then go to data. load the article, you will get DOI.

If your journal is already provided the DOI, then no need to Generate again but yes, if your paper has not then followed the below steps:

1) go to add research.

2) go to add DATA.

3) load paper/ research article.

4) click on generate DOI.

5) Ok

does every book chapter has DOI?

I do not see that RG generates the DOI.

go to your article first--> there a down errow right side nere share button -->click on that select edit.

I also tried, once it was shown option Generate DOI, and generated successfully, but from next time onward it was not shown

I cannot see that RG is generated doi as it used to be. Any hint on that?

The option to generare a DOI within Researchgate seems to have been removed for publications already uploaded. I have now spent two hours trying to figure this out, with no success.

I have a research paper that I cannot publish, so I uploaded it to ResearchGate. None of the document types matched "unpublished research paper" so I selected "Article" as the nearest approximation. There is an option to change the type, but NONE of the possible types allows a DOI to be generated.

To try to work around this, I re-uploaded the paper. At the upload stage, there is a different menu for document type, and I was able to select Other | Research Item. While creating this new entity, the web site gives the option to generate a new DOI. I did this, and then Removed the new item (because it duplicated the existing one), and then tried to apply the DOI to the old copy of the paper, but the ResearchGate software refused it because the DOI had previously used.

So, it seems I have to choose between keeping the existing publication page, and having no DOI, or creating a new publication page and losing the discussion and download count attached to the existing publication page.

Does anyone know any way to add or generate a DOI to my existing paper?

you can get free DOI via this link https://figshare.com/

Funnily though I still cannot figure out how to proceed even uploading a file as public. The generate a DOI option is not even displayed. RG is becoming not very friendly environment it seems. Thanks for hints though. Kind regards

In a case that you still want to generate DOI for your article at RG, read carefully instructions provided here (ResearchGate DOIs): https://explore.researchgate.net/display/support/ResearchGate+DOIs

Yesterday I was able to generate ResearchGate DOIs for my thesis. It is important to add: you must have a single research item. While I had two research items for my thesis, I was not able to generate ResearchGate DOIs for it...
